Question

PLEASE HELP ME ASAP!!!!!

Answer 1

Answer:

First off lets note that this is an iscocleles triangle since the 2 base angles are equal. Additionally, we know that the 2 sides adjacent to the base are equal in iscocleles triangles. Therefore, RP=RQ

With that in mind, lets solve:

If RP=RQ then we can make the equation $5x-4 = x+4$ by using substitution

Now, we can solve for x:

$5x-4 = x+4$

$5x-x-4=x-x+4$

$4x-4 = 4$

$4x-4+4 = 4+4$

$4x = 8$

$4x/4=8/4$

$x=2$

Now that we know what x is equal to we can solve for PR

$PR = 5(2)-4$

$PR = 10-4$

$PR = 6$

Hope this helped!
