Solve for the first variable in one of the equations, then substitute the result into the other equation. (4,2) or x=4 y=2
Answer: a × ba × c = a (bc) = 0
a × ba × c = 2019-2019 = 0
Step-by-step explanation:
The little rectangle in the top right means the angle is a right angle which equals 90 degrees.
This also means all the other angles are also 90 degrees.
Solve for x:
2x+8 = 90
Subtract 8 from both sides:
2x = 82
Divide both sides by 2:
x = 82/2
x = 41
