Answer:

1.

x = 24

m = 112

z = 44

y = 72

2.

x = 35

Explanation:

Number 1

Finding x

- Total angle in a triangle is 180.

- QVS = triangle

180 = ∠Q + ∠V + x

180 = 73 + 83 + x

x = 180 -73 - 83

x = 24

Finding m

- Total angle in a straight line is 180

- RW is a straight line

180 = m + ∠U

180 = m + 68

m = 180 - 68

m = 112

Finding z

- Total angle in a triangle is 180.

- RUS = triangle

180 = m + x + z

180 = 112 + 24 + z

z = 180 - 112 - 24

z = 44

Finding y

- Total angle in a triangle is 180.

- RWT = triangle

180 = z + y + ∠W

180 = 44 + y + 64

y = 180 - 44 - 64

y = 72

Number 2

- Total angle in a triangle is 180.

- Total angle in a straight line is 180.

180 = (180 -120) + 85 + x

180 = 60 + 85 + x

x = 180 - 60 - 85

x = 35
