Question

In triangle PQR . PQ = PR. If angle P = 55 degree, the measure of angle of Q and R​

Answer 1

Step-by-step explanation:

PQ=PR

angle Q= angle R

In triangle PQR,

angle P+ angle Q+ angle R =180°

angle P + angle Q+ angle Q=180°

2 angle Q = 125°

angle Q = angle P = 62.5°

Answer 2

Answer:

angle Q = angle R = 65.5°

Step-by-step explanation:

P+Q+R = 180° ( ASP )

55°+Q+Q = 180° ( Q=R )

2Q = 180°-55° = 125°

Q = 125/2 = 62.5°
