Answer:
Step-by-step explanation:
∠ABC is marked as right angle, 90°.
∠ABD and ∠CBD are complementary angles, so their sum is 90°.
- m∠ABD = 90° - m∠CBD = 90° - 51° = 39°
I think it’s 39 cuz we have to subtract it by 180(supplementary angles) plus the angle is an obtuse angle(meaning more than 0 but less than 90)
