What’s the answer guys

Step-by-step explanation:

Since this is a right angle triangle we can apply trigonometry formulae

SOH, CAH and TOA

In this case, we are going to apply Sine because we have opposite and hypotenuse

Then,

Sinθ=opposite/hypotenuse

Sin20=x/18

Cross multiply

x=18sin20

x=6.156

x is approximately 6.2 to the nearest tenths

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
