ill be asking 10 questions
whoever has the best answer in any of these ill give brainliest :D

Step-by-step explanation:

m = 3

4m - 1 = 4(3) - 1 = 12 - 1 = 11

5m - 4 = 5(3) - 4 = 15 - 4 = 11

4m - 1 = 5m - 4

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
