In the figure shown, suppose m ZABC=n and mZABD = 2(mZDBC). The angle bisector of ZDBC is BE. What is m ZEBC?

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

the answer would be 0.54
