_ (repeating)

3. d=3.16

4. v=1.4

5. b=3

Step-by-step explanation:

3) d= 1.9

4) v= 1.4

5) b= 6

Step-by-step explanation:

On 3, you divide the 5 to have the D be alone

same thing with 4

On 5, you add the -3 to the other side to keep numbers together, and the -3 becomes positive

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
