Answer 1

@jim_thompson5910

Answer 2

no its 67

Answer 3

How did you get that?

Answer 4

angle O and angle Q are supplementary (since we have an inscribed quadrilateral)

Answer 5

O + Q = 180

(x+17) + (6x-5) = 180

x = ??

Answer 6

obvious estimating but hold up ill show steps

Answer 7

7x + 12 = 180

24?

Answer 8

no that's wrong

Answer 9

yes x = 24

but that's not the last step

Answer 10

you use x = 24 to compute angle QRO

Answer 11

oh

Answer 12

How do I do that?

Answer 13

on the pic, it shows that QRO is 2x+19

Answer 14

2x + 19 = 24?

Answer 15

more like 2x + 19 turns into 2*(24) + 19

you found that x = 24, so replace every 'x' with 24

then evaluate

Answer 16

oh uh on every formula on qro?

Answer 17

48+19=67

Answer 18

yes

Answer 19

yay
