X=3 or 3.5, I know that it isn't a direct answer but you asked this question yesterday and have gotten nothing so I will help narrow it down for you.
Answer:
x = 13.75
Step-by-step explanation:
a right-angled triangle.
so, we use Pythagoras
c² = a² + b²
where c is the Hypotenuse (the side opposite of the 90 degree angle).
so, in our case
17² = 10² + x²
289 = 100 + x²
189 = x²
x = 13.75
Answer:
Whole numbers, integers, rational numbers, and real numbers
The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.
To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.
To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.
Finally, round the number you get to the nearest tenth.
Answer:
2
Step-by-step explanation:
Since triangles ABC and ADE are similar by AA (they share angle A and a right angle), their ratio of sides must be equal. Therefore:

Multiply both sides by 2:

Multiply both sides by x+2:

Subtract 2 from both sides:
