9/64 simplified is also still 9/64 (0.140625 in decimal form)
Step-by-step explanation:
Hi there!

To solve, we can use right triangle trigonometry.
Recall that:
sin = O/H, cos = A/H, tan = O/A.
For angle G, HF is its OPPOSITE side, and FG is the hypotenuse.
Therefore, we must use sine to evaluate:
sinG = 14 / 17
sin⁻¹ (14/17) = ∠G. Evaluate using a calculator.
∠G ≈ 55.44°
There are always 180° in a triangle, so to work out the missing angle, you add up the angles you have and do 180 - that answer.
So it would be:
79 + 37 = 116
180 - 116 = 64.
y = 64 :)
