Question

In triangle ABC, angle A is double than angel B but angle C is 5 less than angel A. (Take y to be angle B).
Note:Remember that the sum of angles of a triangle is 180 degrees ​

Answer 1

Answer:A=74,B=37,C=69 Here is your answer

Answer 2

Answer:

Angle A = 74°

Angle B = 37°

Angle C = 69°

Step-by-step explanation:

Sum of all angles of triangle is 180°

Let the angle be A,B,C

Let angle B = y

angle A is double of angle B = 2y

angle C is 5 less than angle A = 2y - 5

A+B+C =180

2y+y+2y-5=180

5y-5=180

5y=180+5

5y= 185

y=185/5

y=37

Angle A=2y=2 × 37=74°

Angle B=y=37°

Angle C= 2y-5=2(37)-5=74-5=69°
