Aformula for finding the perimeter of a rectangle is =2+2 p = 2 l + 2 w . if you know the perimeter () ( p ) and width () ( w ) of a rectangle, which formula can you use to find the length () ( l ) ?

e) none of the above because the measure of angle cba is 101°

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,

pls ask

c. side angle side. u shares the same sides
