Answer 1

Answer:

m∠1 = 50°

m∠2 = 130°

Step-by-step explanation:

There is a formula:

$\text{angle} = \frac{1}{2} (\text{intercepted arc}_1 + \text{intercepted arc}_2)$

$\text{m} \angle 1 = \frac{1}{2} (53^\circ + 47^\circ)$

$\text{m} \angle 1 = \frac{1}{2} (100^\circ)$

$\text{m} \angle 1 = 50^\circ$

Angle 1 and angle 2 together form a straight angle, which measures 180°. Angle 1 and angle 2 are suplementary angles.

$\text{m} \angle 1 + \text{m} \angle 2 = 180^\circ$

$50^\circ + \text{m} \angle 2 = 180^\circ$

$\text{m} \angle 2 = 180^\circ - 50^\circ$

$\text{m} \angle 2 = 130^\circ$
