LEARNING TASK 3:

Directions: Given that b ∥ c with d as

transversal. Find the value of x in the

following.





1. ∠4 = 5x, ∠5 = 120°

2. ∠1 = 100°, ∠7 = 10x

3. ∠2 = 3x - 10, ∠6= x + 30

4. ∠4 = 3x + 10, ∠6= 2x + 20

5. ∠1 = 7x + 9, ∠5 = 5x + 31

Plssss I need this now​

Explanation:

1. Angle 5 = 120 degree

Angle 5 = Angle 6 ( alternate exterior angles are equal )

Therfore, Angle 6 = 120 degree

Angle 6 = Angle 4 ( Vertically opposite angles are equal )

Therfore, Angle 4 = 120 degree

Angle 4 = 5x

120 = 5x

120/5 = x

40 = x

Therefore x = 40 degree.

2. Angle 1 = 100 degree

Angle 1 = Angle 7 ( vertically opposite angles are equal )

Therefore, Angle 7 = 100 degree

Angle 7 = 10x

100 = 10x

100/10 = x

10 = x

Therefore x = 10 degree

I want some more time for this question.
