An isosceles triangle has two equal sides (or three, technically) and two equal angles (or three, technically). The equal sides are called legs, and the third side is the base. ... The angle between the two legs is called the vertex angle. :))

The ratio of an angle to its supplement is 3:5. Find the angle and it's supplement.

Call one of the angles = x

The other one is 180 - x

They are in the ratio of 3 to 5

Equation

3/5 = x / (180 - x)

Solve

3/5 = x / (180 - x) Cross Multiply

3*(180 - x) = 5x

540 - 3x = 5x Add 3x to both sixes

540 = 5x + 3x

540 = 8x

Divide both sides by 8

540 / 8 = x

x = 67.5

One angle is 67.5

The supplement is 180 - 67.5 = 112.5

Check

67.5/112.5 = 0.6 which is the same thing as 3/5

So since x= sand bags replace x with 0 so 7y=105 is left divide by 7 and you get y=15 so 15 bags
