Question 429939: in a triangle ABC, angle B is 5 times angle A and angle c is 3 degress less than 4 times angle a.
Answer by Gogonati(855) (Show Source): You can put this solution on YOUR website!
Solution:Let x degree angle A, then angle B=5x degree, and angle C=4x-3 degree.
Since the sum of angles of triangle is 180 degree, we write the equation:
x+5x+4x-3=180 => 10x=183 => x=18.3
Answer:Angle A=18.3 degree, B=5X18.3=91.5 degree and C=4X18.3-3=70.2 degree.
Done.
