Triangle XYZ is equilateral with vertices located on circle W.
Which measurements are correct? Select two options.
mXY = 60°
myz = 120°
mzx = 180°
m ZXWZ = 60°
mZYWZ = 120°

Step-by-step explanation:

we know that

An equilateral triangle has three equal sides and three equal interior angles. The measure of each interior angle is equal to 60 degrees.

step 1

Find the measure of arc YZ

Remember that

The inscribed angle is half that of the arc comprising

so

In this problem

step 2

Find the measure of angle YWZ

we know that

-----> by central angle

therefore

see the attached figure to better understand the problem

50-38=12
