Me with geometry
i need finding the equations to these questions. i don't understand it but i'm required to show work even though we went through all the answers in class. heres a pic

15. 9 and 54; 16. 14 and 50; 17. 7 and 62;18. 3 and 50

Step-by-step explanation:

If QR bisects ∠PQS, ∠PQR = ∠RQS

15.

∠PQR = ∠RQS

∠PQS = 2∠PQR = 2 × 27 = 54

16.

∠PQS = 2∠PQR

∠PQS = 4×14 - 6 =  56 - 6 = 50

17 .

∠PQR = ∠SQR

∠PQR = 5×7 - 4  =  35 - 4 = 31

∠PQS = 2∠PQR = 2 × 31 = 62

18.

∠PQR = ∠SQR

∠PQR = 8×3 + 1 = 24 + 1 = 25

∠PQS = 2∠PQR = 2 × 25 = 50

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

11

step-by-step explanation:

32.50-7.50=25

225/25=11
