Question

find the value of x

d:6​

Answer 1

$\sf{\qquad\qquad\huge\underline{{\sf Answer}}}$

Let's solve for x ~

$\qquad \sf  \dashrightarrow \: 5x = 3x + 12$

[ by vertical opposite angle pair ]

$\qquad \sf  \dashrightarrow \: 5x - 3x = 12$

$\qquad \sf  \dashrightarrow \: 2x = 12$

$\qquad \sf  \dashrightarrow \: x = 12 \div 2$

$\qquad \sf  \dashrightarrow \: x = 6$

Therefore, the correct choice is D. 6

Answer 2

Answer: D) 6

Step-by-Step Solution:

We know, (5x)° and (3x + 12)° are Vertically Opposite Angles and Vertically Opposite Angles are Equal.

Therefore,
5x = 3x + 12
5x - 3x = 12
2x = 12
x = 12/2
=> x = 6

Therefore, x = 6
