Answer:
<C = 20
Step-by-step explanation:
We know sum of all three angles of a triangle is always 180
So
Angle A + Angle B + Angle C = 180
84 + 76 + <C = 180
160 + <C = 180
<C = 180-160
<C =20

GIVEN :-
- Angle ( A ) of triangle ABC = 84°
- Angle ( B ) of triangle ABC = 76°
TO FIND :-
- Third angle of triangle ABC ( C )
SOLUTION :-
▪︎By angle sum property of triangle ,
=> A + B + c = 180°
=> 84° + 76° + c = 180°
=> c = 180° - 160°
=> c = 20°
Hence the value of angle c is 20°.
ADDITIONAL INFORMATION :-
▪︎ pythagoras theorem = it is a theorem which is always used in Right angled triangle .
▪︎it was discovered by pythagorean.
=> AB² + BC² = AC²
It means ,
(hypotenuse)² = (Base)² + (Perpendicular)².
