Question

two angles of atriangle are in the ratio 4 isto 5. if the sum of these angles is equal to the third angle find the angles

Answer 1

Answer:

Let the two angels be 4x and 5x respectively.

The third angle=the sun of first and second angle

third angle=4x +5x

=9x

Then,

4x+5x+9x= 180(sum of all angels of triangle)

18x= 180

x= 180÷18

x= 10

angels are 40,50and90
