Problema Solution
One angle of a triangle is 10 degrees greater tahn a second angle and is 40 degrees less than the third angle. Find the size of each angle of the triangle.
Answer provided by our tutors
let the one angle be x
then the second angle = x - 10
and third angle = x + 40
but sum of all angles = 180
hence,
x + x - 10 + x + 40 = 180
or 3x = 150
x = 50 degree
hence the angles are,
50, 40 and 90 degrees
