Answer:x+y=8
Step-by-step explanation:the line has an x intercept that is in between the points
Step-by-step explanation:
all angles of a triangle sum to 180
180 = 15x + 24x +21x
180=60x
solve for x
then substitute that for 24(x) to get the angle
Answer:

Step-by-step explanation:
we have

Adds the terms
Group terms that contain the same variable

Combine like terms

where

therefore

A^2+b^2=c^2
24^2=12^2+x^2
sqrt(576-144)=x
sqrt(432)=x
12sqrt(3)=x
the answer is c
220 miles in 4 h = 55 mph multiply this by 5280 to get feet per hour then divide this by 60 to get ft/min
