Question

Find the value of x in each of the following diagrams:​

Answer 1

Answer:

35, 25

Step-by-step explanation:

(I)

2x +x = 105( exterior angle property)

( exterior angle property) 3x=105

x=35

(ii)

2x+3x=125 ( exterior angle property)

2x+3x=125 ( exterior angle property)5x=125

2x+3x=125 ( exterior angle property)5x=125x=25

Answer 2

Step-by-step explanation:

I. 75 + 2x + x = 180°

3x = 105 ( there is one property of it too, something like sum of 2 angles is equal to the exterior angle, I'm little forgetting it, you search it)

x = 35°

2. 55+ 3x + 2x = 180° ( I'm using sum of all angles is 180°)

5x = 125

x = 25°
