Answer:
A
Step-by-step explanation:
Reflecting it across the lines will bring the triangle on to the other triangles. This will show that when the triangle goes under a transformation such as reflection, the angles will stay the same.
16.2
18/25= 21/x
18x=525
525/18 = 29.16
29.4
x = 58
Step-by-step
d is parallel to m => (2x-26) ° and 90 ° are Alternate interior angles
2x - 26 = 90
2x = 90 + 26
2x = 116
