Answer:
x = 43.7°
Step-by-step explanation:
Reference angle (θ) = x°
Opposite side length = 43
Adjacent side length = 45
Apply the trigonometric function, TOA, which is:
Tan θ = Opp/Adj
Substitute
[tex] Tan(x) = \frac{43}{45} [/tex]
[tex] x = Tan^{-1}(\frac{43}{45}) [/tex]
x = 43.7° (nearesth tenth)
