Answer:
choice c
Step-by-step explanation:
take the right triangles.
if hypotenuse on the line forms 125° on other side, then within triangle it forms 55° . 180-125 = 55
so the another angle within right triangle is 35 ° which is formed at the top of triangle.
taking both right triangles it will 35+35 = 70
2w° + 70 = 360
r° = 360-70= 290°
