Angle B is 32 degrees
This triangle is an isosceles triangle so two sides are equal, angle A and angle C are equal so 74+74=148 and then a triangle equals 180 degrees so you subtract the angles of A and C to find B. 180-148=32
Answer:
The expression equivalent to the given complex fraction is
Step-by-step explanation:
An easy way to solve the complex fraction is to solve the numerator and denominator separately.
Numerator:
Denominator:
Solving the complex fraction:
![[\frac{-2}{x} + \frac{5}{y}] / [\frac{3}{y} + \frac{-2}{x}]\\= [\frac{-2y + 5x}{xy}] / [\frac{3x - 2y}{xy}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B-2%7D%7Bx%7D%20%2B%20%5Cfrac%7B5%7D%7By%7D%5D%20%2F%20%5B%5Cfrac%7B3%7D%7By%7D%20%2B%20%5Cfrac%7B-2%7D%7Bx%7D%5D%5C%5C%3D%20%5B%5Cfrac%7B-2y%20%2B%205x%7D%7Bxy%7D%5D%20%2F%20%5B%5Cfrac%7B3x%20-%202y%7D%7Bxy%7D%5D)
Common terms in the numerator and denominator cancels each other(Cross multiplication) :
Let's denote students in D = in the drama club , S<span> = in a sports team </span>
<span>P(D) = 85/330 </span>
<span>P(S) = 200/330 </span>
<span>
P(D and S) = 60/300 </span>
<span>
P(D or S) = P(D) + P(S) - P(D and S) </span><span>= 85/330 + 200/330 - 60/330 = 15/22 </span>
<span>
P(neither D nor S) = 1- 15/22 </span><span>= 7/22</span>
I am pretty sure the answer is c
