Question

PQR is an isosceles traingle in which PQ=PR and P= 58° calculate Q

Answer 1

Answer:

WE KNOW THAT SUM OF TRIANGLE=180

HERE PQ=PR

THEREFORE,ANGLE P=ANGLE R

THEREFORE 58+58+Q=180

Q=180-116

Q=64

Answer 2

Answer:

as PQ=PR,then Q=R

and P=58

then P+R+Q=180

58+R+R=180(as Q=R)

2R=180-58

2R=122

R=122÷2

R=61

therefore,Q= 61( as Q=R)
