The ratio of the measures of the measures of the angles of a triangle is 2 : 3 : 5 . Find the measure of the smallest angle of the triangle.
Answers
Answer:
The smallest angle of the triangle is 36°.
Step-by-step explanation:
The angle sum property of a triangle = 180°
The ratio of the measures of the angles of a triangle = 2 : 3 : 5
= 2x+3x+5x = 10x
➡ 2/10 × 180° = 36 degree
➡ 3/10 × 180° = 54 degree
➡ 5/10 × 180° = 90 degree
36° < 54° < 90°
Therefore, the smallest angle of the triangle is 36°.

Step by step explanation : ⤵️
Given :
. Ratio of measure of three angles of triangle are : 2:3:5
To find :
. Measure of smallest angle of this given triangle.
Explanation :
➝ Before finding our answer, We have to Find out the measure of all angles.
Let the angles of this triangle = 2x, 3x And 5x
Now,
we can say that ,
2x + 3x + 5x = 180° ---( sum of interior angle of triangle= 180°)
HENCE, Solve this equation =
2x + 3x + 5x = 180°
=> 10x = 180°
=> x = 180/10
=> x = 18°
So, We have the value of x = 18°
Now, We can find out the measure of all angles of triangle by putting the value of x in it.
. 2x
➝ 2 × 18 = 36°
so, the one Angle of this triangle = 36°
. 3x
➝ 3 × 18 = 54°
so, second Angle = 54°
. 5x
➝ 5 × 18 = 90°
so, third angle = 90°
Hence,
The measure of all angles of triangle are as :-
36° , 54° , 90°
Now,
question asked to find smallest angle of triangle.
So,
in this solution, We can see that the smallest angle is 36°
so,
Answer :- 36°
