Question

In∆ PQR ,P=70°,Q=65° then find R ​

Answer 1

AnswEr :

➟ Sum of All Angles of ∆PQR = P + Q + R

➟ 180° = 70° + 65° + R

➟ 180° = 135° + R

➟ R = 180° - 135°

➟ R = 45°

Answer 2

Answer:

in triangle PQR ,P=70°,Q=65°,

R=45

Step-by-step explanation:

R=180-P+Q

R=180-135

R=45

hence, R=45°
