Step-by-step explanation:
what do u need help solve
Answer:
tanI = 
Step-by-step explanation:
We require to calculate GH using Pythagoras' identity in the right triangle.
GH² + GI² = HI²
GH² + 5² = (
)²
GH² + 25 = 95 ( subtract 25 from both sides )
GH² = 70 ( take square root of both sides )
GH = 
Then
tanI =
=
= 
Option A
x+8=-3
x+8-8=-3-8
x=-11
Hope I didn't mess up for your sake!
