a) ABD and CBD are Supplementary angles and need to equal 180 degrees

Subtract 117 from 180 for CBD:

CBD = 180 - 117 = 63 degrees

b) In triangles the the shortest side would be opposite the shortest angle.

Since angle D is 56 degrees ( the smallest inside angle) then side BC would be the shortest side.

c) The side opposite the largest angle would be the longest.

Angle B is 63 degrees ( the largest) so side CD is the longest.

Find the slope of the graphed line

Anna [14]

Answer:

Step-by-step explanation:

Pick two points on the line

(0,-5) and (1,-1)

We can find the slope using

m = (y2-y1)/(x2-x1)

= ( -1 - -5)/(1 - 0)

(-1+5)/(1-0)

4/1

= 4
