Question

angle A of triangle ABC equal to sum of other two angles also ratio of measure of angle B to that of C is 4:5 find three angles​

Answer 1

10,40,50 r 3 angles of triangle. abc

Answer 2

Answer:

Step-by-step explanation:

Let the ratio be x

Angle A=4x +5x

Angle B=4x

Angle C=5x

Atq

5x+4x+(4x+5x)=180 (Angle Sum Property)

=9x+9x=180

=18x=180

X=180/18=10

Therefore

Angle A=90 degrees

Angle B=40 degrees

Angle C=50 degrees
