Question
In a triangle ABC, angle B is three times angle A and angle C is 5 degrees less than 6 times angle A. Find the size of the angles.
Answers
B = 3A
C = 6A -5
Since triangles have 180 degrees:
A + 3A + 6A - 5 = 180
Solve for A and then insert that value into the first two equations to solve for b and C.
C = 6A -5
Since triangles have 180 degrees:
A + 3A + 6A - 5 = 180
Solve for A and then insert that value into the first two equations to solve for b and C.
