Step-by-step explanation:
When the sum of two angles is equal to 90 degrees, they are called complementary angles.
So
x + x + 50° = 90°
2x = 90° - 50°
2x = 40°
x = 40°/2
x = 20°
x + 50 = 20 + 50 = 70°

Answer:
d = (-9/13)
Step-by-step explanation:
13d + 8 = -1
-8 -8
13d = -9
÷13 ÷13
d = ( -9/ 13 )
I hope this helps!
Answer:
y = (1/2)x - 3
Step-by-step explanation:
slope-intercept form: y =mx + b
m - slope,
b - y - intercept.
m = 1/2
b= - 3
y = (1/2)x - 3
If the center of dilation is point O, then A is the midpoint of OA' and O is
O = 2A -A' = 2(0, 0) -(5, 5)
O = (-5, -5)
This coincides with point C.
