Answer 2

Question :

The three angles of a triangle are in the ratio 3:4:5 then find the value of all

angles.

Given:

• The angles of the triangle are in the ratio of 3:4:5

$\sf\pink{Let's\:do\:it\:mate\:! }$

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

we know,

The sum of all the tree angles of a triangle is 180°

Therefore,

3x+4x+5x= 180

12x = 180

x = 15

Hence

the angles will be :

$\small\bf\red{➟The\:first\:angle=3x} \\ \small\bf\red{ = 3 \times 15} \\ \small\bf\red{ = 45}$

$\small\bf\green{➟The\:second\:angle=4x} \\ \small\bf\green{ = 4 \times 15} \\ \small\bf\green{ = 60}$

$\small\bf\purple{➟The\:third\:angle = \: 5x} \\ \small\bf\purple{ = 5 \times 15} \\ \small\bf\purple{ = 75}$
