Answer:
Step-by-step explanation:
The transformation is a reflection across the y-axis
A reflection across the y-axis is produced by putting a negative sign in front of the x.
180 - 90 = 90.
x + 2x = 90
3x = 90
x = 30
One acute angle is 30, the other is 60.
4 1/3 there you go hope I helped
Step-by-step explanation:
5x-17 and 3x-11 are supplementary angles
They add up to 180 degrees
5x-17 + 3x - 11 = 180
8x - 28 = 180
8x= 208
x= 26
3x-11, 90, and 2y + 5 added together equal 180
3x-11 + 90 + 2y + 5 = 180
3(26) - 11 + 2y + 5 = 90
78 - 6 + 2y = 90
72 + 2y = 90
2y = 18
y = 9
I hope this helps!!!
