Answer:
x = 46
Step-by-step explanation:
Here, we want to get the value of the angle marked x
From the diagram given , the two angles that are other than x can be gotten from the value of their supplements
Angles on a straight line are supplementary as they add up to 180
Thus, mathematically;
(180-130) + (180-96) + x = 180
50 + 84 + x = 180
x = 180-50-84 = 46
Answer:
-5/2
Step-by-step explanation:
In order to find the slope of a perpendicular line: negate the reciprocal of the original slope
The probability the first marble will be blue is 28/40
The probability the second marble will be red is 12/39
The reason is because 28 + 12 = 40, so this makes the denominator for our first outcome, but then a marble is removed making our denominator 39 because 40-1 = 39.
