The sum of all the angles in a triangle is 180°.
There is a right angle -> a 90° angle on the hypotenuse of the largest triangle (the largest being the one that contains both smaller triangles)

To solve this problem, you don't really need to solve y.
Next to the 48° angle, you have two of the same angles, both x variables.
The sum of these three angles has to be 180°48 + 2x = 180 \\ 2x = 180 - 48 \\ 2x = 132 \\ x = 66

Now that we have x, we can calculate the value of z.
We add the value of x and the 90° angle, we later subtract it from 180°

Calculating the value of z:
66 + 90 = 156 \\ 180 - 156 = 24 \\ z = 24

If you really want to know the value of y, you just add up the 90° angle and the 48°, then subtract that from 180°
90 + 48 = 138 \\ 180 - 138 = 42 \\ y = 42

What is the equation for a line
USPshnik [31]

Answer:

y = mx + b

Step-by-step explanation:

y represents the dependent variable (value you are getting).

m represents the slope of the line.

x represents the independent variable (what you are changing).

b represents the y-intercept, or the y value when x is zero.

The board of an internet start up company has sixteen members. if one person is in charge of research and one is in charge of ma
Brilliant_brown [7]

The number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members is <u>240 ways</u>. Computed using permutations.

The permutation is the way of choosing a set of objects from a larger set of objects in a specific sequence.

If we are choosing r number of objects, from n number of objects in a specific sequence, then we follow permutation, and it is given as:

nPr = n!{(n - r)!}.

In the question, we are asked to find the number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members.

Since the position is to be chosen in a specific order, we will follow permutation.

The number of positions to be chosen (r) = 2.

The number of members (n) = 16.

Thus, the number of ways is given as:

nPr = n!{(n - r)!},

or, 16P2 = 16!{(16 - 2)!},

or, 16P2 = 16!/14! = 15*16 = 240.

Thus, the number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members is <u>240 ways</u>. Computed using permutations.

H(4 1/2, -3 1/4) x (3 3/4, -1 3/4) what the midpoint of hx
shtirl [24]

Answer:

(3 7/8, 2 3/4)

Step-by-step explanation:

To find the midpoint, the formula is (x1-x2)/2 and (y1-y2)/2. So, in this case, our x1 is 4 1/2 and our x2 is -3 1/4. Subtract x2 from x1 and you will get 7 3/4. Then, divide by 2 to get 3 7/8. This is our x-coordinate.

Our y1 is 3 3/4 and our y2 is -1 3/4. Subtract y2 from y1 to get 5 1/2. Then divide by two to get 2 3/4. This is our y-coordinate.

Now we have our x and y coordinates.

(3 7/8, 2 3/4)
