Question

if one angle of a triangle is 55 degree and the other two angles are in the ratio of 2 is to 3 find the other two angles​

Answer 1

☆ Given :-

• One angle of triangle = 55°
• Other two angles are in ratio 2:3

☆ To find :-

• Other two angles.

☆ Solution :-

Let the angles in ratio be 2x and 3x respectively.

• Angle sum property of traingle

ㅤ‎ㅤ

ㅤ‎ㅤ‎✭Sum of all the angles of ∆ =180° ✭

ㅤ‎ㅤ‎ㅤ‎ㅤ55° + 2x + 3x = 180°

ㅤ‎ㅤ‎ㅤ‎ㅤ‎➯ 5x = 180 - 55

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ➯ 5x = 125

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎➯ x = 125/5

ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎➯ x = 25 °

★ Other angles are :-

• 2x = 2(25) = 50°

• 3x = 3(25) = 75°
