Find the value of x.

Step-by-step explanation:

Drop an altitude from the left angle so that it is perpendicular to x

The hypotenuse created by this altitude is 15 cm

The 28 degree angle is opposite the altitude.

Sin(28) = opposite / hypotenuse

opposite = the altitude

hypotenuse = 15 cm

Reference angle = 28 degrees.

Sin(28) = altitude / 15     Multiply both sides by 15

15 sin(28) = altitude

Sin(28) = 0.4695

altitude = 15*0.4695

altitude = 7.0421

Now we can solve for x

Area = 1/2 altitude * x

Area = 1/2 * 7.0421 * x

60 cm^2 = 3.521 * x                        Divide both sides by 3.521

60 / 3.521 = x

x = 17.04

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
