Start with x:
Since x and 57º make a straight line, x+57 = 180 (because a line is 180º). This says x=123º
Now for y:
Because lines m and n are parallel, y and 57º are alternate interior angles and have the same measure. y=57º
Finish with z:
Since y and z make a straight line, can you finish that one from here?
Answer:
48 people
Step-by-step explanation:
The amount of money we have is 500
We have to pay 15 for insurance and 10 per person
500 =15+10p where p is the number of people
Subtract 15 from each side
500-15=15-15+10p
485 = 10p
Divide by 10
485/10 = 10p/10
48.5 = p
We can have 48 since we cannot have part of a person
