What can you say about the marked angles AThe marked angles are supplementary The two angles add to 180 BThe marked angles are complementary add to 90 in a righ class=

Respuesta :

the marked angles are complementary → B

All 3 triangles are right with one angle = 90°

the sum of the angles in a triangle = 180°

thus the remaining 2 marked angles sum to 90°, thus are complementary
