The measure of angle 7 is

is 29 because I think the total has to be 180 and 151 is an obtuse angle so 180-151 =29

if this is incorrect can anyone explain

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,
