2) Find the measure of LA in the
triangle given below
​

Answer 1

Question:

Find the measure of < A in the given triangle.

Answer:

40°

Given:

< A = 2x

< B = 120°

< C = x

To find:

< A

Solution:

< A + < B + < C = 180° (Angle sum property)

2x + 120° + x = 180°

3x + 120° = 180°

3x = 180° - 120°

= 60°

x = ⁶⁰/3

= 20°

< A = 2x

= 2 × 20°

= 40°
