Question

In ∆ ABC, angle A-60°, angle B-100° then find angle C​

Answer 1

Answer:

<c = 20°

Step-by-step explanation:

Sum of angles of a triangle = 180° ( angle sum property )

So, 100°+60°+<c = 180°

Or, 160°+<c = 180°

Or, <c = 180°-160° = 20°

Answer 2

Answer:

Angle c= 20°

Step-by-step explanation:

sum of all angles of a triangle is= 180°

let angle c be = x°

so,

=> 180= (x+60+100)°

=> 180= (x+160)°

=> x= (180-160)°

=> x= 20°
