Question

if ab is parallel to cd then
angle 1=(5x - 45)degree and angle 5 = (3x + 15)degree find angle1 and angle 5​

Answer 1

Answer:

Hey frnd...

Here is ur ans...

Step-by-step explanation:

As angle 1 and angle 5 are corresponding angles thus they are equal...

Thus

angle 1 = angle 5 ........(1)equation

Given angle 1 = (5x -45)

angle 5 = 3x + 15

Put these values in (1) equation

5x - 45 = 3x + 15

5x - 3x = 45 + 15

2x = 60

x = 30

Thus angle 1 = 5x - 45

= 5(30) - 45

= 105 = angle 5

Hope this helps u..
