Using the pythagoras theorem for a right-angled triangle:-
x^2 = 13*2 - 9^2 = 88
x = sqrt 88 = 2 sqrt 22
<span> 6(3x+8)+32+12x </span>Final result : 10 • (3x + 8)
Step by step solution :<span>Step 1 :</span><span>Equation at the end of step 1 :</span> (6 • (3x + 8) + 32) + 12x
<span>Step 2 :</span><span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
30x + 80 = 10 • (3x + 8)
Final result : 10 • (3x + 8)

-11x² + 2x = 10
-11x² + 2x - 10 = 10 - 10
-11x² + 2x - 10 = 0
x = <u>-(2) +/- √((2)² - 4(-11)(-10))</u>
2(-11)
x = <u>-2 +/- √(4 - 440)</u>
-22
x = <u>-2 +/- √(-436)
</u> -22<u>
</u>x = <u>-2 +/- 2i√(109)
</u> -22
x = <u>-2 + 2i√(109</u>) x = <u>-2 - 2i√(109)</u>
-22 -22
x = ¹/₁₁ - ¹/₁₁i√(109) x = ¹/₁₁ + ¹/₁₁i√(109)

The answer to this is 9 miles. i included my work below
I'm pretty sure it's 73 degrees as well since Quadrilaterals are congruent.
