Answer:
57.1°
Step-by-step explanation:
The sides of the rectangle are adjacent and opposite the angle, so the measure is ...
α = arctan(opposite/adjacent) = arctan(19.2/12.4) ≈ 57.1°
The angle between the diagonal and the short side is about 57.1°.

Answer:
x = 12.63 or x= -0.63
Step-by-step explanation:
<em>From my understanding the question is x² - 12x = 8</em>
<em>This will be solved through a quadratic equation formula.</em>
<em>Step 1: Form a quadratic equation</em>
x² - 12x = 8
x² - 12x - 8 = 0
<em>Step 2: Apply the quadratic formula</em>
a = 1, b = -12, c = -8
x = <u>-b±√b²-4ac</u>
2a
x = <u>-(-12)±√(-12)²-4(1)(-8)</u>
2(1)
<em>Step 3: Find the value of x</em>
x = <u>12±4√(11</u>
2
x = <u>12+4√(11)</u> or x = <u>12-4√(11)</u>
2 2
x = 12.63 or x= -0.63
