Hello!

First, find angle BOA on the protractor. To do this, look for point B, point O, and point A.

Now, we see some markings that mark what degree point B and point A are at. Point B is marked at 60 degrees, and Point A 40 degrees.

Now, all that's left to do, is subtract the two measurements.

60 degrees - 40 degrees = 20 degrees

Therefore, your answer is 20.

Hope this helps!

Answer:

$\frac{3}{4}$ chance of landing on a factor of 24

Step-by-step explanation:

There are 8 sections on the spinner.

The factors of 24 are :

$1,2,3,4,6,8,12,24$

Only $1,2,3,4,6,8$ are expressed on the spinner.

There are $\frac{6}{8}$ or $\frac{3}{4}$ chance you will land on a factor of 24.

4x + 2x = < y

This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).

We have to find X.

As you know:

$3x + 4x + 2x = 180$

because the angles of a triangle add up to 180.

When we add them:

$9x = 180$

$x = \frac{180}{9}$

The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-

$x = 20$

Substitute value of x into 4x and 2x to find the exterior angle:-

4x:

$4(20) = 80$

2x:

$2(20) = 40$

When we add them we get the answer for angle Y:-

$80 + 40 = 120$

Therefore, we can conclude that:

$< y = 120 \: degrees$

Answer:

$(3,2)$

Step-by-step explanation:

The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

$y=-2x+8\\y=x-1$
