Question

In ΔABC, ∠A=76°, ∠B=48°, ∴∠C = ..............Select the correct alternative and fill in the blank in the given statement.
(A) 66°
(B) 56°
(C) 124°
(D) 28°

Answer 1

sum of angle of three sides of a triangle is always equal to 180, then

x+76+48=180

x=56

Answer 2

Answer:

∠C = 56°

Step-by-step explanation:

We have to find angle C of the triangle ABC

As we know a triangle has three angles and the sum of the all three interior angles of a triangle is 180°.

So, we can write

∠A +∠B + ∠C = 180°

=> 76° + 48° + ∠C = 180°

=> 124° + ∠C = 180°

=> ∠C = 180° - 124°

=> ∠C = 56°

Hence, the measurement of angle C of triangle ABC is 56°.
