Question

InΔ ABC, <A = 80° , <B = 60°​

Answer 1

Answer:

In ∆ABC =

the sum of all angles in ∆ is 180°

Let <C be x°

60°+80°+X°= 180°

x°= 180°-140°

x°=40°

<C=40°

Answer 2

Answer:

<C=40⁰

Step-by-step explanation:

in a ∆ the sum of 3 side is 180⁰

so<A + <B + <C =180⁰

=>180⁰-(80⁰+60⁰)

=>180⁰-140⁰

=>40⁰
