Answer:
(C)Determine the principal square root of both sides of the equation.
Step-by-step explanation:
Given: Isosceles right triangle XYZ (45°–45°–90° triangle)
To Prove: In a 45°–45°–90° triangle, the hypotenuse is times the length of each leg.
Proof:
Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem,
Since a=b in an isosceles triangle:
Therefore, the next step is to Determine the principal square root of both sides of the equation.
Step-by-step explanation:
-(38/21)
that is the answer
Step-by-step explanation:
it seems the answer is c. 3514 in3
Answer: if you need the relationship angle 6 and 7 are vertical angles
Step-by-step explanation:
Answer:
432 liters
Step-by-step explanation:
Because the container was already 4/9 full, 240 liters is 5/9 of the whole.
1. Convert 5/9 to a decimal and then a percent by dividing the fraction and then multiplying by 100:
5/9 = 0.5556 = 55.56%
2. To determine what number 240 is 55.56% of, write the equation like this:
0.5556x = 240
(In which x = the number you are solving for)
3. Divide both sides of the equation by 0.5556 to isolate the variable.
x =
x = 432 (Don't forget the unit, liters)
4. To check your work, make sure that 240 is 5/9 (55.56%) of 432:
432 × 0.5556 = 240
(Note: Because the fraction converts to a repeating decimal, I had to round it. This means the answer is a very small decimal off from the actual answer that I put.)
