Question

In Triangle ABC, LA=25 LB = 48, LC?

Answer 1

Answer:

ans is 56

Step-by-step explanation:

Given:-

∠B=76°

∠C=48°

∠A=?

As we know that, sum of all angles of a triangle is 180°.

∴∠A+∠B+∠C=180°

⇒∠A+76°+48°=180°

⇒∠A+124°=180°

⇒∠A=180°−124°

⇒∠A=56°

Answer 2

Answer:

In triangle ABC,

LA+LB+LC=180sum of measure of all angle is 180 degree

25+48+LC=180

73+LC=180

LC=180-73

LC=107
