2x+5x+5=180 so x has to be 25
Using the Pythagorean theorem,
.. x^2 = 3^2 +3^2 = (3^2)*2
.. x = √((3^2)*2)
.. x = 3√2 . . . . . . . . matches selection (a)

The hypotenuse of an isosceles right triangle is always √2 times the length of either leg. Since the legs are 3, the hypotenuse is 3√2. You only need to remember this fact to save a bunch of arithmetic.
Step-by-step explanation:
The Pythagorean theorem used in right-angled (equilateral) triangles is a relationship between the sides of a right-angled triangle, where the sum of the square of the legs is equal to the square of the hypotenuse.
If a and b are legs, and c is the hypotenuse, then a2 + b2 = c2.
Because the triangle is right angled, there is no greater side length in the triangle, so an unlimited number of Pythagorean positions can be produced by flipping the sides.
Answer:
9 > b
Step-by-step explanation:
-13 > 5 - 2b
-13 - 5 > -2b
-18/-2 > b
9 > b
1144 Liters of oil.
For every 5 there is 8 used. So 440/5 = 88. 88 units times 8 is 704. 704 synthetic plus 440 natural is 1144 liters of oil total.
