Answer: 6
Step-by-step explanation:
Slope is found by doing:
(x1 and y1 must be from the same ordered pair and x and y must be from the same ordered pair, however point (x1,y1) and (x,y) can be used interchangeably)
Let us say that (x1,y1) is (3,18)
And (x,y) is (5,30)
The answer would be 42 degrees because the total of a triangle is 180 degrees. So you would subtract 180 and 42 (180-42) and that gives you 138 and since the two angles that are touching are the same
Answer:
1= 23
2= 104
3= 90
Step-by-step explanation:
m+f=38
(f-4)^2=m-4
f^2=m IF their age is 30 combined
4^2=16
16=16
Fred is 4, Mabel is 16.
