Solve for x: 
(20x+10)+(3x+9)=180
23x+19=180
23x=161
x=7

Solve for x:
(2x+16)+(3x-6)+(5x-50)=180
10x-40=180
10x=220
x=22

400
Find the smaller angle of rotation between the hands of the clock, whether its positive or negative. Assume the small hand is pointing at 2.
The angle measure of each hour change is 30 degrees. Since 5 hours has passed, this means the smaller angle is 150 degrees and the larger is 210.
400
Solve for y:
60/200=y/40, then : y=12
400
Find the value of cos(-900^o)
-1
400
Suppose that -90<theta<90 . What is the sign of the output of the function of cos(-theta)
it must be positive as this puts cosine either in quadrant 1 or quadrant 4.

Draw a teacher on campus. Points if I can recognize them without writing their name.
Be nice.
500
A pulley rotates through 75° in 1 min. How many rotations does the pulley make in 1 hr?
(75^o)/(1min)*(60min)/(1hr)=(4500^o)/(1hr)
The pulley rotates 4500 degrees in one hour.
It makes 12.5 rotations in 1 hour.
500
If a vertical antenna 45 ft tall casts a shadow 15 ft long, how long would the shadow of a 30-ft pole be at the same time and place?
15/45=x/30, then: x=10
500
Determine the value of the function sec[(2n+1)*90^o]
(2n+1)*90^o results in angles that are on the y-axis. Since sec(theta)=r/x , secant will always be undefined as x=0 .
