9. A building 62 feet tall casts a shadow 21 meters long. At what angle is the sun shining on the building? A. 19.80
B. 18.71
C. 70.20
D. 71.29

71.29°

Step-by-step explanation:

By question its given that , a 62 feet tall tree cast a shadow of 21 m long. We need to find the angle at which the sun is shining on the building .

For this we gonna imagine a right angle triangle . Where , the length of the shadow will be the base of the triangle and the height of the building will be the perpendicular on the triangle .

Here since we have got perpendicular and base , we can use the ratio of tan . We know that tan is defined as perpendicular by base , that is ,

Plug in the respective values , we have ,

Hence the required answer is 71.29° .

the answer is b 1/10

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25
