Answer:
Step-by-step explanation:
To find the angle C given the equation 
, use the "arctan" function [which is the inverse function of tangent] on both sides of the equation as shown below:
This can be rounded to the nearest degree as:
Short answer: 60°
Explanation: All inner angle of a triangle add up to 180° so 180° - 60° - 60° = 60°
Subtracting the 2 already given angels must be subtracted from 180° to know the final angle
Let’s change the equation into
y=mx+b
5x-6y=13 Subtract 5x on both sides
-6y=-5x+13 Then divide by -6 on both sides
Y=5/6x-13/6
m will be your slope
so:
Slope=5/6

Answer:
Step-by-step explanation:
A
The marble is red. There are 6 red marbles out of ten. So the answer is
6/10 = 0.60
B
Red: 1 3 5
Blue: 1 3
So there are 5 ways that you can draw an odd number. The problem is that they are not evenly distributed.
Red: 1/2 * 3/6 = 1/4 = 0.25
Blue: 1/2 * 2/4 = 0.25
Red + blue = 1/4 + 1/4 = 1/2
You could have gotten 1/2 by taking 5/10 but that won't always work.
C
