in triangle abc angle b is 5x angle a and c is 16 degree less than 4 times angle a the size of angle a b c in decimal is

To find the sizes of angles A, B, and C in triangle ABC, we can set up a system of equations based on the given conditions.

Let's assume angle A is represented by 'a' (in degrees).

According to the first condition, angle B is 5 times angle A. So, B = 5a.

According to the second condition, angle C is 16 degrees less than 4 times angle A. So, C = 4a - 16.

To find the size of each angle, we need to solve this system of equations.

However, we're missing some information to solve the system completely. We need either a known angle or a relationship between the angles (such as being complementary or supplementary) to find the specific values of A, B, and C.

Could you please provide any additional information or clarify any missing details?
