Answer 1

Answer:

answers are

1. x = 60

2. x = 90

3. x = 60

4. x = 10

Answer 2

Step-by-step explanation:

1)x+45°=105°(Exterior angle sum property)

x=105°-45°

x=60°

2)x=50°(Vertically opposite angles)

x+y+40=180

50+y+40=180

y+90=180

y=180-90

y=90

4)(x)²=(6)²+(8)²

x²=36+64

x²=100

x=√100

x=10cm
