Please if you can try your best and help solve this

x = 47.5

Step-by-step explanation:

The vertical angle theorem states that if two angles are vertical, they are congruent, so the two angles you gave are congruent.

2x + 5 = 100

2x = 95

x = 47.5

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,
