Problema Solution

The smallest angle in a triangle is half the largest angle.the middle angle measures 30 degrees less than the largest angle.find the measure of each angle

Answer provided by our tutors

let x, y, and z be the angles of the triangle such that x < y < z


x + y + z = 180


the smallest angle in a triangle is half the largest angle:


x = (1/2)z


the middle angle measures 30 degrees less than the largest angle:


y = z - 30


by solving the system of equations


x + y + z = 180


x = (1/2)z


y = z - 30


we find


x = 42 degrees


y = 54 degrees


z = 84 degrees
