Question

The angles of a triangle are in the ratio 3:2:7. Then write the name of the triangle and find the smallest angle of the triangle.​

Answer 1

Answer:

it's a scalene triangle

let the angles be 3x, 2x and 7x

angle sun of a triangle is 180 degrees

so, 2x+3x+7x= 180

12x=180

X=180÷12

X=15

2x=15×2

=30

which is the smallest angle of the triangle

hope this helps!! :)

Answer 2

Answer:

solution: Given ratio 3: 2:7

To find angle

let x.

2x+3x+7x=180°

12x=180°

x=15°

Angles are 2x=2×15=30°

3x=3×15=45°

7x=7×15=105°

Answer is 30° 45° 105°
