For
(x1,y1) and (x2,y2)
slope=(y2-y1)/(x2-x1)

(1,-4)
(4,2)
x1=1
y1=-4
x2=4
y2=2

slope=(2-(-4))/(4-1)=(2+4)/3=6/3=2

slope=2

D.) is 13/5 it got cut off<br> HELP NEEDED<br> [10 points up!]
vodomira [7]

It would be A. You can find this out by using SOH CAH TOA,

SOH means sin= opposite/hypotenuse

CAH mean cos= adjacent/hypotenuse

TOA means tangent= opposite/adjacent

You would use CAH since you are trying to find cos∠C

You would have cos∠C=10/26.

26 is the hypotenuse since it is opposite the right angle and is the biggest side.

10 is the adjacent since it is right next to C

You would simplify this down to 5/13 by dividing by 2.

This gives you A.

Answer:

1,395 sq feet

Step-by-step explanation:

lets start with the area of the green cube b×h. 15×15=225. 225×5= 1125. I got five because there are 5 visible faces on the cube. to find the area of a triangle you use the formula 1/2 bh 9×15= 135 multiply that by 2 instead of one half because you have four triangular faces. add your areas together and you get 1395

\sf \longmapsto \: 2x  +  21 = 3

\sf \longmapsto2x = 3 - 21

\sf \longmapsto2x =  - 18

\sf \longmapsto \: x =  \frac{ - 18}{2}
