Question

determine the measures of all unknown angles on the figure

Answer 1

Answer:

All 3 angles of a triangle are 160°.

$x = 180 - (73 + 75) = 32$

And then the triangle is combined by two figures (triangle and a figure with four angles)

We can define y° by subtracting x° and 26 from 180

$y = 180 - (26 + 32) = 122$

We can define z by subtracting y° from 180 (y°+z°=180)

$z = 180 - 122 = 58$
