Question

Find the measure of the indicated angle in each triangle.

Answer 1

$\sf \: Sum_{(All \: Angles)}=180\degree$

$\sf =\angle B=180-(46+90)$

$\sf =\angle B=180-136$

$\therefore\sf \angle B=44$

Answer 2

Answer:

Step-by-step explanation:

Sum of all angles of triangle = 180

∠B + 46 + 90 = 180

              ∠B = 180 - 90 - 46

∠B = 44
