Question

What is the value of x, shown below?

A) 10
B) 12
C) 14
D) 60

Answer 1

B)12

Explanation:

60=5x-10

+10 +10

70=5x

÷5 ÷5

x=12

Answer 2

The answer would be C) 14
since two intercepted lines always have equal opposite angles, 60= 5x-10.
so, if we input 14 as x
60=5(14)-10
60=70-10
60=60
So answer C) 14 is correct.
