Given:

m∠WYX = 20°

m∠XYZ = 135°

To find:

The measure of arc WXZ.

Solution:

m∠WYZ = m∠WYX + m∠XYZ

m∠WYZ = 20° + 135°

m∠WYZ = 155°

The measure of inscribed angle is half of the intercepted arc.


$\Rightarrow m \angle WYZ = (1)/(2) m (ar WXZ)


$\Rightarrow 155^\circ = (1)/(2) m (ar WXZ)

Multiply by 2 on both sides.


$\Rightarrow 2* 155^\circ = 2 * (1)/(2) m (ar WXZ)


$\Rightarrow 310^\circ = m (ar WXZ)

The measure of arc WXZ IS 310°.
