Given:

[tex]\cos \angle A=\dfrac{342}{1000}[/tex]

To find:

The measure of angle A to the nearest degree.

Solution:

We have,

[tex]\cos \angle A=\dfrac{342}{1000}[/tex]

It can be written as

[tex]\angle A=\cos ^{-1}\dfrac{342}{1000}[/tex]

[tex]\angle A=70.00123^\circ[/tex]

[tex]\angle A=70^\circ[/tex]

Therefore, the measure of angle A to the nearest degree is 70 degrees.

Answer:

The answer is x=6, y=3

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of y opposite(−1)⋅(4x−7y)=(−1)(3)x−7y=−15

Simplify.

−4x+7y=−3x−7y=−15

Add the two equations together to eliminate y from the system.−4x+7y=−3+x−7y=−15−3x=−18

Divide each term by −3 and simplify.

x = 6

Substitute the value found for x into one of the original equations, then solve for y.

y = 3

The solution to the independent system of equations can be represented as a point.(6,3)

The result can be shown in multiple forms.

Point Form: (6,3)

Equation Form: x=6, y=3

Answer:

Step-by-step explanation:

0.40beta%2Bbeta=180-5

1.40beta=175

beta=175%2F1.40

highlight%28beta=125%29�

then alpha%2B125=180 =>alpha=180-125 =>highlight%28alpha=55%29

The required values of angles are 125 and 55.

When two straight lines come together at a point, they produce an angle, which is represented by the symbol.

Given that,

Two angles are supplementary to each other.

Let angles are α and β.

According to given condition,

α + β = 180      (1)

Also, the measure of one angle α is 5 greater than 40% of the other.

α = 0.4 β + 5      (2)

Substitute the value of α in equation (1),

0.4 β + 5 + β = 180

1.4 β = 175

β = 175 / 1.4 = 125

The value of α =0.4 x 125 + 5 = 50 + 5 = 55

The value of angle α and β are 125 and 55.

Step-by-step explanation:

3 ( x - 3 ) = 5x - 4 + 3 ( 7 - x )

3x-9 = 5x-4 + 21 - 3x

collect like terms

3x-9 = 2x +17

move the terms

3x-2x = 17+9

x=26

Answer:

26

Step-by-step explanation:

3 (x-3) = 5x - 4 + 3 (7-x)

3x - 9 = 5x - 4 + 21 - 3x

3x - 9 = 5x - 3x + 17

3x - 9 = 2x + 17

3x - 2x = 17 + 9

x = 26

Answer:

If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.

Step-by-step explanation:

a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.

Answer:

Step-by-step explanation:

You know that the three angles of a triangle add up to 180°. If one angle is 38° and another angle is 67°, then the third angle must be 180°-38°-67° = 75°.

You have a straight line across the bottom, and three angles meeting in the middle of it. Those three angles add up to 180°. One of them is 75°, another is 50°, so the third angle must be 180°-75°-50° = 55°.

That leaves you with one unknown angle. ? = 180°-40°-55° = 85°

Answer:

very simple 0.0007 = 7 / 10000 lol

Step-by-step explanation:

hope this is helpful!

angle 1 = 180-110 = 70 degrees (linnear pair)

angle 2= 180-115 = 65 degrees (linnear pair)

angle 3 = angle 2 = 65 degrees (corresponding angles)

angle 4= 180 - angle 3 = 180-65 = 115 degrees (linnear pair)

(your teacher might not like this, depends on the cituation, but use 180 degrees in triangle to get 7)

angle 7 = 180 -angle1 -angle 2= 180-70-65= 45 degrees

angle 6 = angle 7 = 45 degrees ( vertical angles)

angle 8= 180- angle 7= 180-45 = 135 ( linnear pair)

angle 9 =angle 6 = 45 degrees (corresponding angles)

angle 5=angle 9=45 degrees (vertical angles)

Answer:

150120.83 ; 40 ; 1800

Step-by-step explanation:

Amount of share per person = x

Number of persons = y

x = k/y

k = constant of proportionality

k = xy

257,350 * 7 = 1801450

k = 1801450

If there are 12 persons ; y = 12

x = k/y

x = 1801450 / 12

x = 150120.83

2.) weight on Mars = m

Weight in earth = e

m α e

m = ke

48 = 120k

k = 48 / 120

k = 0.4

m = 0.4 * 100

m = 40

3.)

I α pt

I = kpt

600 = k * 10000 * 2

i believe the answer is A.

Step-by-step explanation: Because the angle PQS is not a 90 degree angle it should equal 180 degrees, it is now lowered down to the answers A. and B. Answer B. has 2x and answer A. has just x. if it were to be 2x then the x would  have to represent 30 degrees but the point plotted x does not equal 30 degrees therefore leaving the last answer as A. x-60=180
