Question

In APQR, P=70°,_Q=30°
then which of the following
statement is true ?

1 . PR>PQ > QR
2. QR > PQ > PR
3 . PR < PQ < QR
4. PR> RQ > QR ​

Answer 1

Step-by-step explanation:

Given that PQ=PR then ∠R=∠Q=x

∠P+∠Q+∠R=180

∘x+x+40 ∘ =180 ∘

x=70 ∘ .

∠R=∠Q=70 ∘

.

Answer 2

Given :

• In PQR, P = 70°, Q = 30°

To find :

• What is the longest side .

Solution :

< P = 70°

< Q = 30°

We know, that

<P + <Q + <R =180

70+ 30+<R = 180

<R = 80

Now, the side opposite to 2R is longest or

PQ is longest side
