The perimeter of a rectangular pool is 140yd. If the length is 10yd more than the width find the length/width.

The smallest angle in a triangle measures 90 less than the largest angle. the middle angle measures 60 less than angles. find the 3 measures

Length = 10 +w

Perimeter = 2l + 2w = 2(10 +w) + 2w = 20 + 4w = 140 yd

120 yd = 4w

w = 30 yd

l = 10 +30 = 40 yd


a + b + c = 180

a = c - 90

b =c - 60

c - 90 + c - 60 + c = 180

3c - 150 = 180

3c = 330

c = 110

a = 110 - 90 = 20

b = 110 - 60 = 50
