For a complimentary pair of angles i.e a+b=90 degrees, then cos a= sin b
so;
3x+2=4x-10
2+10=4x-3x
x=12.0

What is the slope of the line?

Talja [164]

Answer:

Step-by-step explanation:

The line intersects at (0, -3) and (2, 1). Slope is m. $m= \frac{y2 - y1}{x2 - x1}$

Sub your values in. $\frac{1--3}{2-0} or \frac{4}{2} or \frac{2}{1}$

Your slope is 2.

jok3333 [9.3K]

False.

The volume of a cylinder is how much space it takes up INSIDE. You would use volume to measure how much you can put something inside (like water)

Surface area measures the OUTSIDE of a shape. In this case, you'd use surface area to determine how much paper he needs.
