Question

triangle or not?
(iv) If two angles of a triangle are 50°and 60° then find the value of third angle of that triangle.
(1) What is the measure of the supplement of each of the following angles?
(a) 1000
(b) 90°​

Answer 1

Answer:

(iv) sum of all angles=180

50+60+x=180(let 3rd angle be x)

110+x=180

x=180-110

x=70

3rd angle=70

(1)(a)180-100=80

(b)180-90=100

Hope this helps!
