Answer:
A = 77.74 ft
B = 70 ft
C = 104.62 ft
D = 42°
F = 42°
Step-by-step explanation:
Please find attached an image of the question the question
F = 42°
D = 42° (alternate angles are equal)
b = 70 feet
to determine the value of A which is the adjacent side and given the value of the opposite side, tan can be used
Tan 42 = opposite / adjacent
0.9004 = 70 / adjacent
adjacent = 70 / 0.9004
= 77.74 ft
to determine the value of C which is the hypotenuse and given the value of the opposite side, sin can be used
Sin 42 = opposite / hypotenuse
0.6991 = 70 / hypotenuse
hypotenuse = 70 / 0.6691
104.62 ft
