Question

Find the value of "x" in the following
​

Answer 1

(a) 60° (b) 125°

Step-by-step explanation:-

a)

Given are three
`x`'s, so,

`3x = 180`(As all sides of triangle add upto 180°)

`= > x = (180)/(3)`

`= > x = 60`

Hence, value of x is 60°

b)

Given two interior angles(55°,70°) & one exterior angle(
`x`°)

`= > x° = (55 + 70)°`

`= > x° = 125°`

Hence, value of x is 125°
