Question

a) write the ratio of the sides of the triangle in the figure. b) Which is the smallest angle in this triangle.? What is its measure?​

Answer 1

The angles of the triangle are in the ratio: 2:4:3

Let the angles be 2x,4x,3x

By Angle sum property,

2x+4x+3x=180

9x=180

x=20

Thus, angles are, 40

Thus, the smallest angle = 40

Answer 2

Answer:

Angles of a triangle are in the ratio 2 4 3 The smallest angle of the triangle is a 60 B 40 C 80 D 20

(b) Given, the ratio of angles of a triangle is 2 : 4 : 3. Let the angles of a triangle be ∠A, ∠B and ∠C. Hence, the smallest angle of a triangle is 40°.
