<span>$\mathrm{Periodicity\:of}\:\sin\left(2x-15\right)+\cos\left(x-12\right):\quad2\pi$</span>
<span>Use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.
</span>Mark an arc through the sides of the angle. Let the arc intersect the rays at A and B. Continue the arc on past B for a distance.
<span>Set the compass at B, and to the width of AB. </span>
<span>Still with the compass at B, mark an arc to intersect the first arc at C. </span>
<span>Now you have AB = BC. </span>
<span>Since the radius OA=OB=OC, angles AOB and BOC are congruent.</span>
Answer:
y = 25h
Step-by-step explanation:
y is the total pay she received.
25 is the amount of hours she worked, and h is the hourly pay. If she is paid $10 per hour then she will receive $250 in pay.

Answer:
x = 1
z = 1/2
Step-by-step explanation:
z = 3/y
z = 3/6
z = 1/2
x = 2z
x = 2(1/2)
x = 1
