खालील विधानातील रिकाम्या जागा भरण्यासाठी दिलेल्या पर्यायांपैकी अचूक पर्याय निवडा: ΔABC मध्ये ∠A = 76°, ∠B = 48°, तर ∠C चे माप ........ आहे.(A) 66°

(B) 56°

(C) 124°

(D) 28°

Question in English :

Choose the appropriate option and fill in the blank.

In ∆ ABC, ∠A = 76°, ∠B = 48°, then , ∠C = ?

(A) 66°

(B) 56°

(C) 124°

(D) 28°

Solution :

Sum of measures of all angles of a triangle is 180°.

∠A + ∠B + ∠C = 180°

76° + 48° + ∠C = 180°

∠C = 180° - 124°

∠C = 56°

Therefore, ∠C = 56°

Opt. (B) is the answer.

\underline{\mathfrak{\huge{Your\:Answer:}}}

It's given that :-

/_A = 76°
/_B = 48°

And, we need to find :-

/_C = ?

So, here, we can use the Angle Sum Property of a triangle, which says that :-

The sum of all the angles of a triangle is always equal to 180°.

Using this property, we can write that :-

/_A + /_B + /_C = 180°

We are already given with the values of /_A and /_B. So, we can easily find the value of /_C. Put the given values, and then solve the formed equation :-

76° + 48° + /_C = 180°

=》 124° + /_C = 180°

=》 /_C = 180° - 124°

=》 /_C = 56°

\mathfrak{The\:final\:Answer = B.\:56}°
