Question

EASY! which equation can be used to solve x in the diagram??

a) 13x - 5x = 180

b) 5x + 13x = 90

c) 5x + 13x = 180

d) 5x = 13x

no links picture above

Answer 1

C) 5x + 13x = 180

Explanation:

As, the sum of the angles of the above diagram is 180 °

So if we add them we get 180°

So, 5x + 13x = 180°

So option (C) is right
