Question

In ∆PQR, P = 700, Q = 650 then find R. ​

Answer 1

Step-by-step explanation:

In △PQR, ∠P=50

∘

, ∠R=70

∘

Sum of angles of the triangle = 180

∠P+∠Q+∠R=180

50+∠Q+70=180

∠Q=60

∘

Side opposite smaller angle is shorter and side opposite to larger angle is larger.

Hence, QR is the smallest side, PQ is the largest side.

Answer 2

Step-by-step explanation:

p=700

q=650

R=?

we know that sum of all the angles in a triange is 180°

so,

p+q+r=180°

700+650+R=180°

1350+R=180°

R=180-1350

-1170
