Question

∠PQR and ∠ABC are supplementary angles and ∠PQR is eleven times as large as ∠ABC. Determine the measure of each angle.

Answer 1

x+y =180

x=11y

Answer 2

x= angle PQR

y= angle ABC

Answer 3

solve simultaneously

Answer 4

no

Answer 5

no 11x+y=180

Answer 6

still wrong

Answer 7

sub the second into the first

11y +y =180 , 12y = 180

Answer 8

15

Answer 9

y=15

sub into eqn 2 , x =11 x 15 = 165

Answer 10

which one is the 2nd eqn?
