Answer:
A° = 44.42°
Step-by-step explanation:
Soh Coh Toa
Soh: sin(theta) = Opp/Hyp
Coh: cos(theta) = Adj/Hyp
Toa: tan(theta) = Opp/Adj
We are using Coh: cos(theta) = Adj/Hyp because we need to find Angle A and that 5 is Adjacent and 7 is the Hypotenuse.
cos(A°) = 5/7
A° = cos^-1 (5/7)
A° ≈ 44.4153086
A° = 44.42°
