We will make ''X'' the result that we are searching for
and ''Y'' how much water Grayson has
So we have : X = Y + 2/5
and : Y = 2/4 - 0.4 = 1/2 - 4/10 = 1/10
So X = 1/10 + 2/5 = 5/10 = 1/2 0f a cup
Answer:
A right triangle
Step-by-step explanation:
It's where the altitudes all intersect. In a right triangle, the legs of the right triangle are the altitudes-- especially evident when the right angle is at the base. The altitude from the hypotenuse to the right angle also passes through the right angle.
You can use the Pythagorean Theorem:
a^2+b^2=c^2
x^2+x^2=(7√2)^2
2x^2=49*2 (combine like terms and square the 7√2)
x^2=49 (divide both sides by 2)
x=7 (square root both sides)
So the equation is 2x^2=98 (simplest form) and x=7
Hope this helps
