Question

Two adjacent angles on a straight line are (3x - 2)° and
(2x + 7)° .Find the value of x​

Answer 1

Answer:

x= 35

Step-by-step explanation:

(3x-2)° + (2x+7)° = 180°(reason: linear pair)

(3x-2)° + (2x+7)° = 180°(reason: linear pair)3x + 2x + 7 - 2 = 180°

(3x-2)° + (2x+7)° = 180°(reason: linear pair)3x + 2x + 7 - 2 = 180°5x + 5 = 180°

(3x-2)° + (2x+7)° = 180°(reason: linear pair)3x + 2x + 7 - 2 = 180°5x + 5 = 180°5x =180 - 5

(3x-2)° + (2x+7)° = 180°(reason: linear pair)3x + 2x + 7 - 2 = 180°5x + 5 = 180°5x =180 - 55x = 175

(3x-2)° + (2x+7)° = 180°(reason: linear pair)3x + 2x + 7 - 2 = 180°5x + 5 = 180°5x =180 - 55x = 175x = 175 ÷5

(3x-2)° + (2x+7)° = 180°(reason: linear pair)3x + 2x + 7 - 2 = 180°5x + 5 = 180°5x =180 - 55x = 175x = 175 ÷5x = 35°
