Answer:
Step-by-step explanation:
Given that:
is a supplement of
.
m = 78°
To find:
m = ?
Solution:
First of all, let us learn about the concept of an angle being a supplement of the other angle.
is known as supplement of
, if sum of the two angles is equal to 180°.
.
For example, angle made on one side by a line intersecting the other line are supplement of each other.
Here, we are given that is a supplement of
.
In other words:
Putting value of :
So, the answer is:
Answer:
a.
b.
Step-by-step explanation:
We are given that two cards are drawn are randomly selected from a standard 52- cards deck.
Total cards=52
Total number of spade cards=13
Probability=
a.The probability of drawing two cards first card is spade and second card is spade without replacement =
The probability of drawing two cards first card is spade and second card is spade=
b. The probability of drawing two cards first is spade and second card is a spade with replacement =
The probability of drawing two cards first is spade and second card is a spade with replacement =
Answer:
(5, 6)
Step-by-step explanation:
First, get both equations into slope-intercept form so they are easier to graph:
The first equation is already in this form, so only do the second equation:
To do this, just solve for y and that should almost always get it in the correct form.
That equation is also now in slope-intercept form.
Now, using the slope and y-intercept in both equations, you can graph them. Using the graph, you can see the solution of this system of equations at (5, 6).
