Find the cosine of angle E.
A) 39/80
B) 39/89
C) 80/39
D) 80/89

Answer:

the answer is 83°

Step-by-step explanation:

by the sum of iner and outer angle=180°

180-126= 54°

x=180-43+54

x=180-97

x=83°

The measure of angle x is 43°.

What is Triangle?

A triangle is a three sided polygon , which has three vertices.

Given that;

In triangle, The value of interior angles are 43° and x°.

And, An exterior angle is 126°.

Since, The sum of two interior angles is equal to the exterior angle of same triangle.

Hence, We can formulate;

43° + x = 126°

Subtract 43° both side;

43° + x - 43° = 126° - 43°

x = 83°

Thus, The measure of angle x is 43°.

=3X+10

Step-by-step explanation:

3c + 3s = 12.50

4c + 2s = 10.00

3S = 12.50-3c

s = 4.17 - c

4c + 2 (4.17-c) = 10.00

2c + 8.34 = 10.00

2c = 1.66

Answer: The height of tree = 15 ft. 6 inches

Step-by-step explanation:

Given: A person's height is 5-ft 3-in = [5 x (12 )+3 ]  inches    [ 1 ft= 12 inches]

= 63 inches      

Their shadow has a length of 3-ft 6-in = [3 x 12+6] inches    

= 42 inches

If a nearby tree has a shadow of length 10-ft 4-in = [10 x 12+4] inches

= 124 inches.

At the same time,

[tex]\dfrac{\text{Height of tree}}{\text{Height of person}}=\dfrac{\text{Length person's shadow}}{\text{Length of tree's shadow}}\\\\\dfrac{\text{Height of tree}}{63}=\dfrac{124}{42}\\\\\Rightarrow\ \text{Height of tree}=\dfrac{124}{42}\times63=186\ inches\\\\=\dfrac{186}{12}= 15.5 ft\ or\ 15 ft.\ 6\ inches.[/tex]

Hence, the height of tree = 15 ft. 6 inches

Start with your exponetial growth formula: y = a(1 + r)^t.

Now, a is going to be your initial amount, r is the rate, and t is the time.

So we have y = $4,000(1 + .02)^7.

Now simplify inside the parenthses first.

So we have y = $4,000(1.02)^7.

Simplifying further gives us y = $4,000(1.14868).

Now use a calculator to get y = $4,594.72

Answer:

20 degrees

Step-by-step explanation:

The line has a total of 180 degrees. So, x+100+3x=180. Then, we subtract 100 from both sides to get x+3x=80. Then, x+3x=4x. So, 4x=80 degrees, and so divide by 4 on both sides and you get x=20 degrees.

Formula of circumference of circle:

2 x pi x radius OR

pi x diameter

Let's use the second method, to find diameter it is radius x 2 = 46

So,

Answer:

perimeter: 10 units

area: 6 square units

Step-by-step explanation:

within the picture point J and point M seem to be 3 units are.

with this assumption, with can infer that both parallel sides are 3 units giving us 6 units for both sides

we can as well as tell that point J and point K seem to be 2 units apart.

with this info we can infer that both parallel sides will be the congruent lenght. which will add up to 4

thus giving us the equation for the area

6 + 4 = (10 units) for the perimeters

for that area we will then do 3 units by 2 units

(3 units for the assumed length and 2 units for the assumed width)

giving us the equation 3×2 = (6 square units)
