Answer:
blackness?
Step-by-step explanation:
Answer: The central angles are always equal to the arc measure. And the inscribed angles is always one-half of the arc measure.
For the problems below, you would have the following answer.
Circle 1: Central 42 and inscribed of 21
Circle 2: Central 66 and inscribed of 33
Circle 3: Central 180 and inscribed of 90
Answer:
See below.
Step-by-step explanation:

A. JL = KL True
B. Line s is perpendicular to JK True
C. Point L is the midpoint of JK True
D. Line s intersects JK at a 180° angle False
E. Line s is parallel to JK False
Answer:
The magnitude of the vertical component of vector u is
The magnitude of the horizontal component of vector u is
Step-by-step explanation:
A vector quantity has, a magnitude and a direction
The horizontal component of vector is ║u║ cos α
The vertical component of vector is ║u║ sin α
∵ The magnitude of vector u is 12 ft
∵ The measure of angle α is 135°
- Substitute the magnitude and the angle in the rule of
each component
∴ = 12 cos(135)
∴ = 12 sin(135)
∵ cos(135) =
∴ = 12 ( )
∴ =
- The magnitude of a number means the number without its sign
∴ The magnitude of the horizontal component of vector u is
∵ sin(135) =
∴ = 12 ( )
∴ =
∴ The magnitude of the vertical component of vector u is
