Question

solve for b

Explanation:

Step1: Calculate angle $a$

Use triangle angle sum property:
$a = 180^\circ - 33^\circ - 70^\circ = 77^\circ$

Step2: Find supplementary angle of $a$

The adjacent angle to $a$ is:
$180^\circ - 77^\circ = 103^\circ$

Step3: Calculate angle $b$

Use triangle angle sum property:
$b = 180^\circ - 103^\circ - 25^\circ = 52^\circ$

Answer:

$52^\circ$
