Question

What is the relationship between Za and Zb?

Answer 1

Answer:

$\boxed{Complementary \: angles}$

Given:

$\angle EAC = \angle a \\ \\ \angle CAB = \angle b \\ \\ \angle DAB = 90 \degree$

Step-by-step explanation:

Two Angles are Complementary when they add up to 90° (a Right Angle).

$= > \angle EAC + \angle CAB + \angle DAB = 180 \degree \\ \\ = > \angle a + \angle b + 90 \degree = 180 \degree \\ \\ = > \angle a + \angle b = 180 \degree - 90 \degree \\ \\ = > \angle a + \angle b = 90\degree$
