Question

HELP ME ASAP PLEASE!!

Answer 1

Answer:

x=3

PR=10

Step-by-step explanation:

This is an isosceles triangle, indicated by the black markers on angles P and Q. This also means that sides PR and QR are equal.

That in mind, to solve for x set the two expressions equal to each other and solve for x.

3x+1=5x-5 (subtract 1 from the left side and 5 from the right. Do the same from both sides)

-2x = -6 (divide by -2)

X=3

To find the measurement for PR, simply plug in the value for x into the equation for PR

3(3) +1

9+1 =10
