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.
Answer:
60%
Step-by-step explanation:
The first step is to divide 27 by 45 to get the answer in decimal form:
27 / 45 = 0.6000
Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:
0.6000 * 100 = 60.00%
(5,-3) is in the fourth quadrant, if it rotates 90 counter clockwise then it will be in the first quadrant. Your x and y values are going to swap, and you need to know what is true about the numbers since they are in the first quadrant. leave a comment if you need more help.
Answer:
a. C=7π
b. C=14π
c. C=21π
d. C=28π
Step-by-step explanation:
To find the circumference, you need to multiply the diameter (d) by π times i.e. C=πd.
