Question

A.12 B.9 C.3 D.24 Please help this is not my best subject

Answer 1

Answer: B.9

Step-by-step explanation:

You know that $\angle A$≅$\angle B$, this means that the measure of the angle A and the measure of the angle B are equal. Then:

$m\angle A=m\angle B$

You know that:

$m\angle A=4x-12$ and $m\angle B=24$

Therefore, you can substitute them into $m\angle A=m\angle B$ :

$4x-12=24$

Now you can solve for the variable "x":

$4x=24+12\\\\4x=36\\\\x=\frac{36}{4}\\\\x=9$

You can observe that this value of "x" matches with the option B.

Answer 2

Answer: The Answer Is 9

Step-by-step explanation:

If 4x - 12 = 24, add 12 to 24, and divide 36 by 4.
