Question

hy mate I need your help !!!!!
please anwer fast"""​

Answer 1

Step-by-step explanation:

14. In triangle PQR

angle PQR =angle PRQ

let PQS and PRT be 1 and 2 respectively

given PQR and PRQ are equal then

PQS+PQR=180⁰ (LINEAR PAIR)-------(1)

PRT+PRQ=180⁰ (LINEAR PAIR)-------(2)

COMPARE EQ 1 AND 2 V GET THAT

angle PQS=PRT

HENCE PROVED

15. angleBAC=35⁰ and angleCDE=53⁰

angle BAC=angleCED=35⁰

in triangleDCE

CED+EDC+DCE=180⁰ ( ANGLE SUM PROP)

35⁰+53⁰+DCE=180⁰

88⁰+DCE=180⁰

DCE=180⁰- 88⁰=92⁰
