Answer:
Angles 5 and angle 2 are supplementary angles
Step-by-step explanation:
Angle 2 and angle 6 are corresponding angles and corresponding angles are equal when we have parallel lines
Angles 5 and angle 6 are supplementary angles since they form a line
Replace angle 6 with angle 2 since they are equal
Angles 5 and angle 2 are supplementary angles
Answer:
A. Cos2x
Step-by-step explanation:
f(x) = sin(x)cos(x) = (1/2) sin(2x) using double angle formula.
f'(x) = ( (1/2)sin(2x) )' = 2(1/2)cos(2x) = cos(2x)

Answer:
153.94 in²
Step-by-step explanation:
The equation for Area is
Area = πr²
Plugging in the value for the radius into r, it will be
(note, r means radius)
Area = π(7)²= 49π ≈ 153.94
The units is -> in² so add that in the end
