Answer:

m∠3 = 143°

Step-by-step explanation:

m∠1 = 53°

m∠2 = 180 - (90 + 53) = 37°

m∠3 = 180 - 37 = 143°

Answer:

143

Step-by-step explanation:

solution:

angle 1 = 53°

angle D = 90°

angle 3 = angle 1+ angle D [sum of two]

= 53°+90° [interior angle is equal ]

=143° [to an exterior angle]

Brett is 75 feet from the base of a building. he measures the angle of elevation to the top of the building and records it as 80

SashulF [63]

This is the concept of trigonometry, we are required to calculate the number of floors the building has given the information above;
# floors=[height of the building]/[height of each floor]
height of each floor=17 ft
let the height of the building be,h.
h is given by;
tan theta=opposite/adjacent
theta=80
opposite=h
adjacent=75 ft
thus
tan 80=h/75
h=75 tan 80
h=425.35 ft
thus the number of floors will be:
425.35/17
=25.020≈25 floors
