Answer:
B. x < 17
Step-by-step explanation:
x is a leg of right triangle ADC, so must have a length less than the hypotenuse. (x < 20)
x is a leg of triangle ABC, so must have a length between 20-17 = 3 and 20+17=37. The first restriction limits x to ...
3 < x < 20 . . . . . allows x ≥ 17
The Pythagorean theorem applied to the right triangle requires ...
x^2 +y^2 = 400
Angle ABC is opposite side AC, which has length 20. Angle BAC is opposite side BC, which has length 17. The longer length of AC means that angle B will always be greater than angle A in triangle ABC.

The only condition that is <em>not necessarily true</em> is ...
x < 17
Answer:
Volume of a cylinder = 549.5 cm³
Step-by-step explanation:
Volume of a cylinder = πr²h
Where,
π = 3.14
Radius, r = 5 cm
Height, h = 7 cm
Volume of a cylinder = πr²h
= 3.14 * (5 cm)² * 7 cm
= 3.14 * 25 cm² * 7 cm
= 549.5 cm³
Volume of a cylinder = 549.5 cm³
Answer:
C=pi x d. 3.14x33 103.62

Answer:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
