Answer:

60 degrees

Step-by-step explanation:

BWA is an isosceles triangle, meaning that BW and WA are equal in length.

Thus, we have that ABW and WAB are congruent to each other.

ABC is a complementary angle, so ABW and CBD add up to 90 degrees.

ABW is 30 degrees, so we have 30 degrees+ CBD=90 degrees.

Subtracting thirty degrees from both sides we get CBD=60 degrees.

Hope this helps!

Find the volume of the rectangular pyramid below.

VMariaS [17]

Answer:

315 yd cubed

Step-by-step explanation:

To find the volume of the pyramid, we first need to consult the equation below. Thebase is for the rectangular portion, then after multiplied by the height it is divided by 3 to get the pyramid.

$\frac{1}{3} (B * H )$

To get the base, we multiply the length by the width.

21 * 9 = 189

189 * 5 = 945

945 divided by 3 = 315

The equation y = 8.1x models the relationship between the number of hours Alexander works, x, and the dollar amount he earns, y.

Katarina [22]

Start the graph at the <em>y</em>-intercept. At 0 hours, he will make $0, so (0, 0) is the <em>y</em>-intercept. From this point, he makes $8.10 an hour; go up 8.1 for every 1 hour you go over on the graph. The graph is attached.
