Question

Q. One of the angles of a triangle is equal to the sum of the remaining two angles. If the ratio of these angles is 4:5, find the angles of the given triangle.​

Answer 1

Answer:

Merry Christmas to you

Answer 2

Answer:

let one of the angle be x

then 2nd and 3rd angles be 4x and 5x

given that one angle is sum of remaining 2 angles

So the angles is 4x +5x=9x

sum of angles in a triangle is 180

therefore 4x+5x+9x=180

18x=180

x=180/18

=10

x=10

4x=40

5x=50

9x=90

the angles in a triangle are 40,50,and90.
