Question

Q.6.One angle of a trianglemeasures30 and the other 2 angles are in the ratio 3:2.Find the angles of the triangle

Answer 1

Answer:

90° and 60°

Step-by-step explanation:

30°+3x+2x=180°

30°+5x=180°

5x=180°-30°

5x=150°

x=150°/5

x=30

3x=3(30)=90°

2x=2(30)=60°

Answer 2

Answer:

Hello

Step-by-step explanation:

Angle A = 30°

Let Angle B and Angle C equal to 3X and 2X respectively.

Now, According to Angles sum property of the triangle.

Angle A+ Angle B+ Angle C = 180°

30° + 3X + 2X = 180°

30° + 5X = 180°

5X = 180°-30°

X= 150°/5

X= 30°

•Angles are;

Angle A= 30°

Angle B= 3×30 = 90°

Angle C= 2×30= 60°
