Question

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 pls!!

Answer 1

Explanation:

C) 5x + 13x = 180°

Because, the angles in the diagram add up to 180° because it's a straight angle

So, the sum of both of them will give 180

So option (C) is right
