Question

In A PQR, PQ = PR, IF P= 40° then Q=.
​

Answer 1

Answer:

Q=70°

Step-by-step explanation:

angle Q= angle R

base angle of an isosceles ∆

P+Q+R=180°

40°+2Q=180

2Q=140°

Q=70°

Answer 2

Step-by-step explanation:

if pq=pr then its a iscosceles triangles so two angles(other than 40) must also be equal .

it means

x+x+40=180

2x=140

x=70 degree so Q =70°
