Question

the angles of a triangle are in the ratio 1:3:5. Find the measure of each one of the angles ​

Answer 1

Answer:

let angles of triangle be X ,3x and 5 x

then

x+3x+5x =180°

so 9x=180°

therefore x=20° and 3x=60°and5x=100°

for this follow me

Answer 2

let the angles of triangle be x,3x,5x

we know that, sum of angles of triangle is 180.

now,we have

x +3x+5x=180

9x=180

x=180/9

x=20

now,x=20

3x=3×20=60

5x=5×20=100

Hence, the required angles of the triangle are 20 degree,60 degree and 100 degree
