<u>Answer:</u>
<h2>
ST = 44.54 ft</h2>
<u>Explanation:</u>
given:
∠T=90° , ∠R=39° and TR = 55 ft
ST = 55×tan(39)
ST = 55×0.80..
ST = 44.54 ft

Answer:
(7, -3)
Step-by-step explanation:
Add the two equations to eliminate x:
7y = -21
Then solve 7y = −21 for y:
= (<em>Divide both sides by 7)</em>
y = -3
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
2y - 3x = -27
Substitute -3 for y in 3y - 3x = -27:
(2)(-3) - 3x = -27
-3x - 6 = -27 (<em>Simplify both sides of the equation</em>)
-3x - 6x + 6x = -27 + 6 (<em>Add 6 to both sides</em>)
-3x = -21
= (<em>Divide both sides by -3</em>)
x = 7
