Answer 1

Answer:

Step-by-step explanation:

b+90+180-153=180

b+90-153=0

b-63=0

b=63 degrees

Answer 2

Answer:

$63^\circ$

Step-by-step explanation:

The asterisk means degree sign in the following solution.

The measure of the smaller angle in the triangle is 180* - 153*.

The measure of b is 180* - (180* - 153*) - 90* (because the sum of angles in a triangle is 180*).

b = 180* - (180* - 153*) - 90* = 153* - 90* = 63*
