Answer:
The measure of angle x is 25 degrees.
Step-by-step explanation:
Since triangle ABC is an isosceles triangle, the measure of angle BAC is equal to the measure of angle ACB. Angle ABC = 80 degrees, leaving 100 degrees to be divided equally for the measures of the other two angles. Now that you know that angle ACB = 50 degrees, you can calculate the value of angle ACD and determine that angle ACD = 130 degrees. Triangle ACD is also an isosceles triangle, and the two equal legs are AC and CD. Since angle ACD = 130 degrees, the other two angles have a total of 50 degrees. Splitting the 50 degrees equally between the two angles gives you 25 degrees as the value of angle CAD, which is labeled "x."
SOLUTION
We will use the formula

Applying we have

Now using a Zscore calculator for 1.370320, we have
P(xHence the answer is 0.9147
AB = x
BC = 3x
AC = 20 inches = AB + BC
Let's plug our values into the equation above.
20 inches = x + 3x
Combine like terms
20 inches = 4x
Divide both sides by 4
5 = x
AB = x = 5 inches
BC = 3x = 3(5) = 15 inches
Here is your answer. In the first bracket it's your X1 and Y1 and second bracket it's your X2 and Y2
Answer:

Solve

We start by converting the division sign to multiplication

Then, we divide -9 by 3
Then, we divide 8 by -4
Multiply -2 and -3 to give final result

Hence,
is equivalent to 6
