Answer:

x = 90
y = 64

Step-by-step explanation:

If we take the arcs to mean that those angles are congruent, then the sum of exterior angles is ...

x° +2y° +75° +67° = 360°

y = 109 -x/2 . . . . . . subtract non-x terms and divide by 2

Because x° forms a linear pair with a right angle, we know ...

x° = 180° -90° = 90°

Then ...

y = 109 -90/2 = 64

The values of x and y are 90 and 64, respectively.

Help please Factorise x²-x-56 its due in 4 minutes

Answer:

(x-8)(x+7)

Step-by-step explanation:

using quadratic formula we have

x= $\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}$

we have:

x^2-x-56=0

a= 1 b=-1 c=-56

so we have:

x=(-(-1)+-sqrt(1^1-4*(1)*(-56)))/(2*1)

x=1+-sqrt(1-4*(-56))/(2)

x=(1+-sqrt(225))/2

x=(1+-15)/2

so we have the roots:

x1=(1+15)/2 =8

x2=(1-15)/2=-7

so the answer is (x-8)(x+7)

After I add up all the numbers and divide them what do I do after?

Novosadov [1.4K]

When finding the mean you add up the numbers that are needed to find the mean and divide them by the amount of numbers you added. For example question 5 you will add 58+58+62+55+49+48 which will equal 330 and then divide it by 6 because there are 6 numbers which is 55.
