<h3>
Answer: 658.3</h3>
==================================================
Explanation:
The adjacent complementary angle to that 28 degree angle is 62 degrees because 62+28 = 90.
If the reference angle is the upper acute angle 62 degrees, then the y is the opposite leg and the side 350 is the adjacent leg.
Use the tangent ratio
tan(angle) = opposite/adjacent
tan(62) = y/350
350*tan(62) = y
y = 350*tan(62)
y = 658.254262871217
y = 658.3

Answer:
y = 2x - 1
Step-by-step explanation:
(4,7) (2,3)
slope = (7-3)/(4-2) = 4/2 = 2
y = 2x + c
when x=4 , y=7
7 = 2(4) + c
c = 7-8 = -1
y = 2x - 1

Answer:
0.495
Explanation:
Given the expression:
![0.55-1.645\sqrt[]{\frac{0.55(1-0.55)}{220}}](https://tex.z-dn.net/?f=0.55-1.645%5Csqrt%5B%5D%7B%5Cfrac%7B0.55%281-0.55%29%7D%7B220%7D%7D)
Begin by simplifying the expression under the radical (square root) sign.
![\begin{gathered} =0.55-1.645\sqrt[]{\frac{0.55(0.45)}{220}} \\ =0.55-1.645\sqrt[]{\frac{0.2475}{220}} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3D0.55-1.645%5Csqrt%5B%5D%7B%5Cfrac%7B0.55%280.45%29%7D%7B220%7D%7D%20%5C%5C%20%3D0.55-1.645%5Csqrt%5B%5D%7B%5Cfrac%7B0.2475%7D%7B220%7D%7D%20%5Cend%7Bgathered%7D)
Using a calculator, we evaluate the radical:
![\begin{gathered} =0.55-1.645\sqrt[]{0.001125} \\ =0.494825 \\ \approx0.495\text{ (to 3 decimal places)} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%3D0.55-1.645%5Csqrt%5B%5D%7B0.001125%7D%20%5C%5C%20%3D0.494825%20%5C%5C%20%5Capprox0.495%5Ctext%7B%20%28to%203%20decimal%20places%29%7D%20%5Cend%7Bgathered%7D)
