In the figure, m and n are rays.
blagie [28]

Answer:

A is correct because 1 and 3 are vertical angles.

B is correct because there are 180 degrees in a triangle. 180-65-55 = 60. Angle 2 is vertical to the third angle, so angle 2 equals 60.

C is incorrect because it is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 ≠ 60.

D is correct because 3 is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 = 120.

In review, A, B, and D are correct.

I hope this helps you =)

#31. I just need to know how you did it! THANK YOU
kirill [66]

Answer:

m=60º

n=30º

Step-by-step explanation:

a triangle is 180º total

an equilateral triangle has all 60º angles

since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º

substituting the values 60+n=90

so n=30

Then since a triangle is 180º you can make an equation that says 180=90+m+n

again substituting 180=90+m+30

60=m

an easy way to check is 180=90+30+60             180=180

What is the median for the following set of data? 2, 3, 6, 8, 9, 10, 11
Inessa05 [86]

Answer:

The median value will be 8.

Step-by-step explanation:

The simplest way to think of a median is as a sort of "middle" value. We want to arrange our numbers from lowest to highest, then select the one in the middle. Here is another example:

3, 5, 2, 7, 3, 9, 1, 4, 7

The first step is to order these numbers from lowest to highest, like so:

1, 2, 3, 3, 4, 5, 7, 7, 9

The number in the middle of this set is 4.

The problem you have presented, as well as the above example, both deal with an odd amount of numbers. Your problem has seven numbers, and the example I gave has nine. For any odd amount of numbers, the median is the value in the middle. But what about an even amount of numbers?

Consider:

9, 4, 3, 7

Let's rearrange this:

3, 4, 7, 9

Now, there will be two "middle" values: 4 and 7. The median value will be the average of these two values:

\text{median} = \frac{4 + 7}{2} = \frac{11}{2} = 5.5

I hope that helps!

Answer fast! I don't understand how to do this. I have a test going on about exponent properties.
qwelly [4]

Answer:

x^4yz

Step-by-step explanation:

\frac{(x^6y^3z^2)}{(x^2y^2z)}    (This can be simplified, because when you divide expressions with exponents that have the same bases, you can subtract the exponents from the one with the corresponding base)

\frac{(x^6y^3z^2)}{(x^2y^2z)}

= (x^(^6^-^2^)y^(^3^-^2^)z^(^2^-^1^))    (Simplify)

= x^4yz
