Name the marked angle in 2 different ways.

​

Two different ways are :

1. ∠RQS

2. ∠SQR

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
