Question

give me answer please​

Answer 1

Answer:

14-x=30 y=90

Step-by-step explanation:

14)A)ΔPOR=ΔSTU

 i- QR=TU (GIVEN 4CM)

ii- ∠PQR=∠STU(60·)

iii-∠PRQ=∠SUT

∴ΔPQR≅ΔSTU BY ASA RULE

B)∠PRQ=∠SUT=30·

∴∠STU+∠SUT+∠TSU=180·

 60+30+Y=180

 90+Y=180

 Y=90

15)ΔPSQ=ΔPSR

   i-PS=PS (COMMON)

   ii- ∠PSQ=∠PSR (90·)

   iii-PQ=PR(GIVEN)

  ∴ΔPSQ≅ΔPSR BY SAS RULE

plz mark as brainliest and drop some thanks

Answer 2

Q.14)

ΔPQR ≅ ΔSTU (ASA)

∠R = ∠U

x = 30°

y + x + 60° = 180°

y = 180 - 90

y = 90°

Q.15)

PR = PQ

∠S = ∠S = 90°

PS = PS (Common Side)

ΔPQS ≅ ΔPRS

(SAS)
