Answer:

Perimeter of Triangle: 6x+15

x=12.5

Step-by-step explanation:

The perimeter is the sum of all of the sides of the triangle.

Hence, the perimeter =3x+3x+15=6x+15

Since the perimeter is 90, 6x+15=90.

Subtract 15 from both sides:

6x+15-15=90-15

6x=75

Divide both sides by 6:

\frac{6x}{6}=\frac{75}{6}

x=12.5

The height of glass 1 is 7.6
so, you find the volume of glass 2,= 26.376
then you subtract the answer from 80 cubic cm to get the volume of glass 1
                           80 - 26.376 = 53.694
then you work backwards to get the height, which is 7.6
