Question

triangle pqr, angle p = 10°, angle q = 65° then find angle r​

Answer 1

Answer:

105

Step-by-step explanation:

Since its a triangle the angles MUST add to 180 thus

10+65=75

180-75=105 and that is the value of  r

*If you want to know that you have solved correctly when you add all angles p+q+r you should get 180

10+65+105=180

Answer 2

using angle sum property of triangle PQR..

==>angle P° + angle Q° + angle R° = 180°

===>10° +  65° +  angle R° =180°

====>75° + angle R° = 180°

=====>angle R° = 180° -  75°

=======>angle R°=105°

hope u got ur answer........
