Question

In triangle PQR,angle P = 60°
angle Q = 45Find angle R.​

Answer 1

Step-by-step explanation:

Let angle R be x So,

angle P + angle Q+ angle R =180(Angle Sum Property of triangle)

60+45+x=180

105+x=180

x=180-105

x=75

Answer 2

Answer:

sum of all angles of a triangle is 180°

P+Q+R = 180°

60°+45°+x° = 180°

105°+x = 180°

x = (180-105)°

x= 75°

so, the third Angle is 75°
