We can know from the pic
2x+38=90
so, x=26
4. 54 + 63 + 54=171
5. 3+3+75=81
6. 20+68=89
7. 120+180=300 x 1.48=$444
Answer:
Step-by-step explanation:
1. rotation 90 degrees clockwise
2.reflection over y axis
3.rotation 180
4.reflection over x axis
5.rotation 90 degrees counter clockwise
Answer:
x-2
The choose (1)
Step-by-step explanation:
(x³-3x²+3x-2)÷(x²-x+1)
(x-2)(x²-x+1) ÷ (x²-x+1)
Delete (x²-x+1)
so = (x-2)
y + (2x -12) = 180 (since they are supplementary angles)
(2x-12) = 96 ( since they are alternate exterior angle)
2x = 96 + 12
2x = 108
x = 108/2
x = 54.
y+( 2x-12)=180
y+(2× 54 -12) = 180
y + (108-12) = 180
y + 96 = 180
y= 180-96
y = 84.
