Question

The angle of a traingle are the ratio 3:4:5. Find them

Answer 1

Answer: 45°, 75°, 60°

Step-by-step explanation:

Given ratio of angles of triangle 3:4:5

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

According to property of triangle,

The sum of interior angles of triangle is 180 degree

So,

3x+ 4x +5x =180

12x =180

x = 180 ÷ 12  = 15

Therefore the angles will be

3x = 3×15 =45"

4x = 4×15 =60"

5x = 5×15 = 75"

Answer 2

Answer:

45,60,75

Step-by-step explanation:

as we know,sum of internal angle of a triangle is=180

now,,we assume,the angles are,3x,4x,5x

so we can write,

3x+4x+5x=180

or,12x=180

or,x=15

thn actually angles are-3#15=45

4#15=60

5#15=75
