Question

5. The acute angles of a triangle are in the ratio 3:4:5.
Find their measures. Identify the type of triangle.​

Answer 1

Answer:

Angles are in the ratio of 3:4:5

Let the angles be 3x,4x,5x

∴3x+4x+5x=180...........Sum of the angles of triangle are 180

o

∴12x=180

∴x=15

Hence, the angles are: 45

Answer 2

Answer:

45°,60°, 75°

SCALENE TRIANGLE

as all the sides are unequal....

Explanation:

Let the measures of the triangle be 3x, 4x, and 5x.

Given,

Total sum of all the angels of a triangle=180°

According to the problem,

3x+4x+5x=180°

12x=180°

x=180°/12

x= 15°

so, 3x=3*15°=45°

4x=4*15°=60°

5x=5*15°=75°
