What does x equal 1/2x+ 4 =9

x = 10

Step-by-step explanation:

1/2 x + 4 = 9

To find the value of x, we first combine like terms

1/2x = 9 - 4

1/2x = 5

Divide both sides by 1/2

x = 5 ÷ 1/2

x = 5 x 2/1

x = 10

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
