-(-9)-11+18 then you remove the parenthesis
9-11+18
answer: 16
Answer:
Step-by-step explanation:
Triangle IGH is a right angle triangle.
From the given right angle triangle
GI represents the hypotenuse of the right angle triangle.
With m∠I as the reference angle,
HI represents the adjacent side of the right angle triangle.
GH represents the opposite side of the right angle triangle.
To determine Hl, we would apply the tangent trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan 42 = 11/HI
0.9HI = 11
HI = 11/0.9
HI = 12.22
The first 3 are functions as their x coordinate (number on the left side of the parentheses) is not repeated in any of the other parentheses
