Question

Determine the measures of all unknown angles on the figure

Answer 1

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`
