Answer: you have to substitute them into the equation
Step-by-step explanation:
example: x = 2y - 6
lets say you test 4/5 so it would be 4 = 2(5) - 6
this equals 4 = 10 - 6 which is true
so that is how you test to see if the equation is right
remember the first number goes to "x" and the second one goes to y

Answer:
D
x=8*cos(34°)=6.632≈6.6
no
800x8%=64
64+800=864
C. 19.47°
The triangle's angles are 90°, 70.53°, and 19.47°.
x + 72 = 180
y = 72 (vertical angles)
x = 108
z = 90 - 72
z = 18
