Answer:
41.4°
Step-by-step explanation:
Reference angle = θ
Hypotenuse = 8
Adjacent = 6
Therefore,
[tex] cos(\theta) = \frac{adj}{hyp} [/tex]
[tex] cos(\theta) = \frac{6}{8} [/tex]
[tex] cos(\theta) = 0.75 [/tex]
[tex] \theta = cos^{-1}(0.75) [/tex]
[tex] \theta = 41.4 degrees [/tex] (nearest tenth)
