Question

plzz answer 25th and 26th

Answer 1

25) In ΔAOD,by angle sum property,
      x+x-6+90=180
 ⇒2x=180-84
      x=96/2=48°
similarly, in ΔBOC, 
4y+3y+6+90=180
⇒7y=180-96
⇒y=84/7= 12°

26) ∵∠x=∠y
⇒180-x=180-y
i.e. ∠QSR=∠PEQ 
in ΔPEQ & ΔRSQ,
PQ=QR
∠QSR=∠PEQ
∠Q=∠Q
∴by AAS congruence rule, 
ΔPEQ ≡ ΔRSQ
by CPCT,
PE=RS
