The Brainliest answer is 40x-72.
8*5=40(add the x because of the variable on the coefficient)
8*9=72, the 72 being negative because of the sign in front of it.
THIS IS EASY. I don't have a calculator on me so bare with me.
1.) 7x - 9 = -4x + 90
7x +9. = -4x. + 9
7x. = -4x. 99
+4x = +4x. + 99
11× = 99
÷ 11. ÷ 11
X = 9
U can solve the rest. Are you serious?
Let x and y be the angles
X= 3•y-8
X+ y = 180
Substitute first relationship in second
3y-8+y=180
4y=180+8
Y =188/4= 47 degrees
X= 180-47=133 degrees
The measure of the large angle is
133 degrees
