Question

find the angle of a triangle which are in ratio 2:3:5​

Answer 1

Answer: 36°,54° and 90°

Step-by-step explanation:

Ratio = 2 : 3 : 5

Angle sum property of triangle says all angles addition is 180 degree. let the angles be as 2x 3x and 5x

==> 2x + 3x + 5x = 180

==> 10x = 180

==> x = 180/10

==> x = 18

One Angle = 2x = 2 × 18 = 36

Second Angle = 3x = 3 × 18 = 54

Third angle = 5x = 5 × 18 = 90

.°. The angle are 36°, 54° and 90°.

Answer 2

Answer:

Let the angles be 2x, 3x, and 5x

B. T. P.

$2x + 3x + 5x = {180}^{0} \\ = > 10x = {180}^{0} \\ = > x = \frac{ {180}^{0} }{10} \\ = > x = {18}^{0}$

Therefore, the angles are :

$= 2x = 2 \times {18}^{0} = {36}^{0 } \\ = 3x = 3 \times {18}^{0} = {54}^{0} \\ = 5x = 5 \times {18}^{0} = {90}^{0}$
