Question

in isosceles PQR, P is the vertex angle. If M Q =8x-3 and mR = 2x+15, find the measure of P

Answer 1

I assume mQ means measure of angle Q
the base angles of an isosceles triangle are equal. that means
8x-3 = 2x+15

can you "solve for x"?

Answer 2

thanks and yes i can

Answer 3

this is multiple steps. once you find x, you have to find mQ (which also be mR)
then find the 3rd angle, which is what they want.

Answer 4

i dont get that part.

Answer 5

did you find a value for x ?

Answer 6

yes

Answer 7

and x = ?

Answer 8

2

Answer 9

try again

Answer 10

its wrong.?

Answer 11

if x =2 then
8x-3 = 2x+15
becomes
8*2 - 3 = 2*2 +15
16-3 = 4+15
13 = 19 , which is not true.

Answer 12

oh thanks i get it now
