Let the angle be x.
Hence, its complement is 90 - x.
x = 3* (90 - x) - 70 = 270 - 3x - 70 = 200 - 3x
4x = 200
x = 50
Thus, the angle is 50°.
Step-by-step explanation:
the last one
x^2+2x+1 R(-5)
Answer: Slope is m = 2/3
Step-by-step explanation:
-You have exactly four points on a table:

-Use the slope formula and use any two points from those four points in order to find the slope:

-The two points I use are
and
for the equation:


So, the slope of the table is
.
I think that (1/4)x+8 would be your algebraic expression.
2.7 would be 2 7/10. Correct?
