Let's first solve for 
: 
At this point it's just a matter of drawing a circle, and mark where the angle is(please excuse my paint skills, but free hand drawing would be even worse). Red line, is 
on the cosines, and both the green and blue lines are valid solutions. The green line is a quarter of a circle, plus 30°, or 120°. The blue one is 3/4 of a circle, minus 30 degrees, or 240°.
Answer:
y=35x+50

yes there will be 10 dollars left
I hope this is good enough:
Answer:
44 degrees
Step-by-step explanation:
Triangles ABC and DBC are congruent (as said in the question), that would make the corresponding parts of the two triangles congruent.
Answer: if you think about b it sounds wrong so the answer is probably A
Step-by-step explanation: you said it wasn’t C or D so between A and B , A makes more sense
Simplify the following:
