Step-by-step explanation:
1.) value of 8: angle 4(5x + 35°) = angle 8
First find x
5x + 35° + 45° = 180°
5x + 80°= 180°
5x = 180° - 80°
5x= 100°
5x/5 = 100/5
x=20°
5x + 35°
5(20°) + 35°
100° + 35° = 135
2.) angle 2 and angle 7(45°) is a corresponding angles meaning, angle 2 = angle 7
angle 2 = 45°
3.) angle 7(45°) is a vertical angle of angle 6 meaning, angle 7(45°) = angle 6
angle 6 = 45°
5.) angle 2 and angle 7(45°) is an alternate exterior angle meaning, angle 2= angle 7(45°)
angle 2= 45°
7.) 5x + 35° + 45° = 180°
5x + 80°= 180°
5x = 180° - 80°
5x= 100°
5x/5 = 100/5
x=20°
