the ratio of the measures of three angles of a triangle 5:7:8. find the measure of each angle of the triangle
Accepted Solution
A:
Let the measures of three angles be 5x, 7x, 8x Sum of angles of a triangle = 180° 5x + 7x+ 8x = 180° 20x = 180 x = 180/20 = 9 First angle = 5x = 5*9 = 45° Second angle = 7x = 7*9 = 63° Third angle = 8x = 8*9 = 72° I hope it is helpful:D
