Question

In the given figure,find x​

Answer 1

Hey mate!!!

By Angle Sum Property,

A + B + C = 180°

$(5x - 60) + (2x + 40) + (3x - 80) = 180 \\ 5x - 60 + 2x + 40 + 3x - 80 = 180 \\ 10x - 100 = 180 \\ 10x = 180 + 100 = 280 \\ x = \frac{280}{10} \\ x = 28$

Answer 2

Answer:

x = 28

Step by step explanation:

By angle sum property,

5x - 60 + 2x + 40 + 3x - 80 = 180

5x + 2x + 3x - 60 + 40 - 80 = 180

10x - 60 - 80 + 40 = 180

10x - 140 + 40 = 180

10x - 100 = 180

10x = 180 + 100

10x = 280

x = 280/10

x = 28
