Answer:

Step-by-step explanation:
<u>Trigonometric ratios</u>

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
= G- A = GF = 2
- H = EG = 4

Answer:
1. x=4+2y/3
2. x=3/4+y/2
Step-by-step explanation:
hope this helped :))
2, because you can round to get the answer.
6x+10y=20
10y=-6x+20
y=-6/10x+20/10
y=-3/5x+2
5x-3y=21
-3y=21-5x
y=21/-3+-5/-3x
y=3/5x-7
Two lines are Perpendicular
