Answer:
∠x = 13.43°
Step-by-step explanation:
area ΔABC = 1/2 ( BD x AC) = 1/2 (22 x AC) = 42
22 x AC = 84 AC = 84/22 = 42/11 = 3.82
CD = BD - BC = 22 - 6 = 16
AD² = AC² + CD² = (3.82)² + 16² = 270.59
AD = 16.45
sin ∠x = AC / AD = 3.82 / 16.45 = 0.2322
∠x = 13.43°

Multiply the first equation by -1 to get -4x - y = --5
Then add the second equation 3x + y = 3
+ ____________
-x = -2 or x = 2
then plug in 2 for x in one of the equations and solve for y 4(2) + y = 5
8 + y = 5
Subtract 8 from both sides y = -3
So x = 2, y = -3 or (2,-3)
