Need help solving for Y

We are going to use tangent function to solve for angle y. Since the angle y is located towards the normal line (not the horizontal line). So
tan y = adjacent side / opposite side
tan y = 8/10
y = arctan 8/10 (use the calculator)
y = 38.66°

in your economics 101 class you have scores of 68,82,87 and 89 on the first four of five tests to earn a grade of a B or higher

Nadusha1986 [10]

(68 + 82 + 87 + 89 + x) / 5 > = 80
(326 + x) / 5 > = 80
326 + x > = 80 * 5
326 + x > = 400
x > = 400 - 326
x > = 74.......u would have to make at least a 74 to earn a B

Answer:

$\large\boxed{4\sqrt{-81}+\sqrt{-25}=41i}$

Step-by-step explanation:

$i=\sqrt{-1}\\\\\sqrt{-81}=\sqrt{(81)(-1)}=\sqrt{81}\cdot\sqrt{-1}=9i\\\\\sqrt{-25}=\sqrt{(25)(-1)}=\sqrt{25}\cdot\sqrt{-1}=5i\\\\4\sqrt{-81}+\sqrt{-25}=4(9i)+5i=36i+5i=41i$
