Question

Q.33 If the angles of a triangle are in the ratio of 2:5:8. then find the value of the smallest angle.
A. 36
B. 18
C. 12
D. 24°​

Answer 1

NAMASTE,

Let the angles be 2x , 5x and 8x

Then,

15x = 180° ( ASP of ∆ )

x = 180/15

x = 12

Hence,

Smallest angle = 2x = 2 × 12 = 24° ANS_✔️

THANK YOU...✌️

Answer 2

Answer:

Step-by-step explanation:

Let the angles be 2x, 5x and 8x

ATQ,

2x+5x+8x=180

=> 15x=180

=> x=180/15

=> x=12

Therefore, 2x= 2x12=12

Hence, the measure of the smallest angle is 12 degrees
