Question

ANSWER TO MY QUESTION WILL BE MARKED BRILLIANT...
QUESTION IS- FIND THE VALUE OF X (2x-5)° AND STATE THE PROPERTY USED.​

Answer 1

Answer:

x = 40 degree

Step-by-step explanation:

x + (2x-5) degree = 115 degree [exterior angle is equal to sum of angles opposite to it]

3x-5 degree = 115 degree

3x = 115 degree + 5 degree

3x = 120 degree

x = 120 degree / 3

x = 40 degree

Answer 2

Answer:

X = 36.6

2x - 5 = 2 × 36.6 - 5 = 68.2

Step-by-step explanation:

X + 2x - 5 = 115°

3x - 5 = 115

3x = 115 - 5

3x = 110

X = 110 ÷ 3

X = 36.6
