Good luck on your assignment..

Answer:

LM =20.00356825

Step-by-step explanation:

We will use the law of sines

sin M        sin N  

-------- = ------------

LN             LM

We can find the measure of N since the sum of the angles of triangles is 180

L+ M+ N =180

53+ 44 + N =180

N =180 - 53-44

N =83

sin 44        sin 83

-------- = ------------

14             LM

Using cross products

LM sin 44 = 14 sin 83

LM = 14 sin 83 / sin 44

LM =20.00356825

Step-by-step explanation:

Answer:

A + D

Step-by-step explanation:

Answer A is three x's (same as original) and answer D, when expanded using the distributive property, equals 2x + 2 + x, which is equal to 3x + 2.

Answer:

x=2

sx = 2 - (2 x 0.04)

sx = 2 - 0.08

sx = 1.92

lx = 2 + (2 x 0.04)

lx = 2 + 0.08

lx = 2.08

Step-by-step explanation:

Answer:

-8, 7

Step-by-step explanation:

Set up an equation.

x² + x = 56

Set the equation equal to zero and factor.

x² + x - 56 = 0

(x + 8)(x - 7) = 0

Solve for x.

x + 8 = 0

x = -8

x - 7 = 0

x = 7

The possible x values are -8 and 7.

Answer & Step-by-step explanation:

The problem tells us that ΔABC ≅ ΔDEF. Since we know that this is true, then we also know that ∠A ≅ ∠D, ∠B ≅ ∠E, and ∠C ≅ ∠F.

So, since we are looking for the measurement of ∠F, then all we have to do is know the measurements of ∠C because they are congruent angles.

So, the measurement of ∠F is 63°

Answer:

r=10.9cm

Q=12cm

S=14.42cm

Step-by-step explanation:

Pythagoras theorem states H²=b²+h²

H-hypotenuse

B-base

h-height

E.g q 4²+3²=HE

H=√25=5

Step-by-step explanation:

A= 1/2 x b x h

A=1/2 x 4.6 x 2.5

A=5.75 CM=5.8 cm

Answer:

[tex]5.8 {cm}^{2} [/tex]

Step-by-step explanation:

[tex]area \\ = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 4.6 \times 2.5 \\ = \frac{11.5}{2} \\ = 5.75 {cm}^{2} [/tex]

round to one decimal.

Answer:

F. 5(12)(7)

Step-by-step explanation:

V=L×W×H

V=7×5×12

=F. V=5(7)(12)

Answer: D

Step-by-step explanation:

Distributive Property is when you want to apply to FOIL method when you are multiplying out the expression. You would have multiple number/terms to multiply out to. The only answer choice that shows this is D.

In D, you are distributing the 5 to 8 and -2. So, you are multiplying 5×8=40 and 5×-2=-10. Then you have 40-10.

A is just multiplying, 5 and 1/5.

B is just multiplying 5 and 1.

C is just Associative Property, changing the parenthesis.

D  shows Distributive Property.

Answer:

Explanation:

C is the not the answer because when there is a minus sign with a number in front of the parenthesis, the numbers in the parenthesis will bave to be solved instead of distributed.

B is not the answer because there are not even parenthesis to empasise the distibution.

A is not the asnwer because the numbers are simply being canceled out into the number 1 with a fraction and a whole number.

Answer:

The side lengths that are the legs are 6 and 12 because the hypotenuse is the largest side length of a triangle (since there are three side lengths shown).  

Answer:

6 & 12

Step-by-step explanation:

In a right triangle, the greatest side length belongs to hypotenuse, other 2 numbers represent the legs

so as per the given, 14 is hypotenuse ans 6 & 12 are legs

Step-by-step explanation:

You need to use trigonometric stuff here. Since you're given the hypotenuse and an angle you can plug that right into an equation.

Recall that sin is opposite over hypotenuse and cos is adjacent over hypotenuse.

[tex]sin(\theta)=\frac{o}{h} \\sin(30)=\frac{x}{14} \\0.5=\frac{x}{14} \\x=7[/tex]

Now that you know the opposite side (DC) you can use tan, too, but I'm going to use cos.

[tex]cos(\theta)=\frac{a}{14} \\cos(30)=\frac{x}{14} \\\frac{\sqrt{3} }{2} =\frac{x}{14} \\x=7\sqrt{3}[/tex]

This is the adjacent side (BC). I put it in its exact value, but in decimal form it's ≈12.124.

Now you can do the perimeter:

[tex]2l+2w\\2(12.124)+2(7)\\24.248+14\\38.25[/tex]

Your answer is the 38.2

Answer:

137 units^2.

Step-by-step explanation:

A and B are positioned according to their coordinates, in the X and Y axes Imagine a right angled triangle, where the actual distance between the two points is the hypotenuse, and the other two sides are the distances in the “X” and “Y” axes that separate the two points.

In the “X” axis, they’re separated by 3 -(-1) units that’s 4…

In the “Y” axis, they’re separated by 4 - (-7) units that’s 11…

Now we have the lengths of two sides of the triangle, we can calculate the length of the hypotenuse… But why would we? we’ve been asked for the area of the square, and adding the areas of the squares on the other two sides gives our answer-

4^2 + 11^ 2 = 16 + 121, = 137 units^2. You didn’t specify units, so we don’t know what the area is, we just have a numerical value.

Answer:

58

Step-by-step explanation:

The distance between (-1,4) and (2,-3) is sqrt 58. Square that to be 58

Answer:

- 5i and 5i

Step-by-step explanation:

The Fundamental theorem of Algebra states that a polynomial of degree 3 has 3 roots, real and/ or complex.

Complex roots occur in conjugate pairs.

Given 2 real roots x = 5, x = - 5

There cannot be complex roots as they occur in pairs which would result in the polynomial having 4 roots instead of 3.
