Answer:
x ≈ 28°
Step-by-step explanation:
We know the hypotenuse (the longest side) and the opposite (the side opposite x) so we can use SOH:
sine x = opposite ÷ hypotenuse
Substitute in the values:
sin x = 7 ÷ 15
sin x = 0.4666...
Now we can do the inverse of sine to find x:
x = [tex]sin^{-1}[/tex](0.466..)
x = 27.818138... ≈ 28°
Hope this helps!
