Question

The angles of a triangle are in a ratio 2:3:7 The measure of the smallest angles is 1 point 90 60 45 30

Answer 1

Step-by-step explanation:

let the required no. be 2x,3x,7x

2x+3x+4x = 180° (sum of triangle)

12X = 180°

x = 15°

smallest angle is 30°

Answer 2

Answer:

✡ Given ✡

✏ The angles of a triangle are in a ratio of 2:3:7

✡ To Find ✡

✏ The smallest angle.

✡ Solution ✡

✏ Let the angles be 2x,3x and 7x

⬛ $\angle$A + $\angle$B + $\angle$C = 180°

=> 2x + 3x + 7x = 180°

=> 12x = 180°

=> x = $\dfrac{180°}{12}$

=> x = 15°

▶ Smallest angles is = 2×15° = 30°
