PLEASE HELP! 20 points!

Answer:

Step-by-step explanation:

The marks on both sides of the triangle shows that the sides are equal. This means that the triangle is an isosceles triangle.

This means that

x = 4

Also, in an isosceles triangle, the base angles are equal. Therefore, the sum of the base angles would be 2y.

The sum of angles in a triangle is 180 degrees. Therefore,

2y + 50 = 180

Subtracting 50 from both sides of the equation, it becomes

2y + 50 - 50 = 180 - 50 = 130

2y = 130

y = 130/2 = 65 degrees.

Answer:

x = 36

Step-by-step explanation:

EAB is a straight line so it equal 180

EAF + FAB = EAB

3x+2x = 180

Combine like terms

5x = 180

Divide each side by 5

5x/5 = 180/5

x = 36

The mean of the data is 18. What number is missing? 21,11,_,27,22,13,16
Ludmilka [50]

The missing number is 16

<em><u>Solution:</u></em>

Given that mean of data is 18

Let "x" be the missing number

The data set is:

21, 11, x , 27, 22, 13, 16

Sum of data set = 21 + 11 + x + 27 + 22 + 13 + 16

Sum of data set = 110 + x

<em><u>The mean is given by formula:</u></em>

Mean = \frac{\text{sum of all numbers}}{\text{total numbers in data set}}

Substituting the values we get,

18 = \frac{110+x}{7}\\\\126 = 110 + x\\\\x = 126 - 110\\\\x = 16

Thus the missing number is 16
