PERSEVERE Find the values of x and y,

Mathematics
1 answer:
Vlad [161]3 years ago
8 0

y² = 8y - 15 (alternate angles are equal)

y² - 8y + 15 = 0

(y - 5)(y - 3) = 0

y = 5 or 3

x + 8y - 15 = 180 (angles in a straight line add up to 180)

when y = 5

x + 40 - 15 = 180

x = 155°

when y = 3

x + 24 - 15 = 180

x = 171°

Tpy6a [65]
You have 20 cookies total in the jar.  The probability of choosing an oatmeal is 4/20, and the probability of choosing a peanut butter cookie is 8/20.  In order to find the probability of pulling a peanut butter cookie OR an oatmeal cookie, we have to add the probabilities together.  8/20 + 4/20 = 12/20 or 6/10 or 3/5.  The answer is C.

How to solve inscribed angles
alisha [4.7K]
If it involves an Arc, the inscribed angle is 1/2 of the measure of the are across from it. If the figure inscribed in a quadrilateral, opposite angles are supplementary (when added together equals 180 degrees) This is all I know :)

X²(2 - 7x) (-x+2)<br> Expand the following exercise
Komok [63]

Answer:

Step-by-step explanation:

Use FOIL method

(2 - 7x)(-x + 2) = 2*(-x) + 2*2 + (-7x)*(-x) + (-7x)*2

                     = -2x + 4 + 7x² - 14x    {Combine like terms}

                   =  7x² - 14x - 2x + 4

                   = 7x² - 16x + 4

x²(2-7x)(-x + 2)= x² (7x² - 16x + 4)

                      = x²*7x² - 16x * x² + 4x²

                      7x^{2+2} -16x^{1+2} + 4x^{2}\\\\= 7x^{4} - 16x^{3} + 4x^{2}
