Answer:

Notice how there is a dash bisecting every line of this triangle. Also keep in mind that the interior angles of any triangle add up to 180°. BEcause there is a dash on each line it is using SSS criterion and showing us that all the side lengths are the same length.

Therefore this is an equilateral triangle. The angles and side lengths of an equilateral triangle are the sane. Therefore every angle in this triangle will be 60°. IN support of this, the 3 angles of 60° add up to 180 meaning this is a valid answer.

So if the m<2=x+69, to get 60 (the measure of all angles) x has to be -9

-9=x

Find the first three terms of the sequence with nth term 3n-2

kykrilka [37]

Answer:

To find out the first three terms of 3n - 2 substitute 1 ,2 and 3 into the equation.

so the three terms a

3(1)-2=1

3(2)-2=6-2=4

3(3)-2=9-2=7

As you can see the sequence goes up in 1,4 and 7.To find out the 10th term you also substitute 10 into the equation so 3(9)-2=18-2=16

so 16 is the tenth term

Hope this helped!

Question 2 of 10

AnnyKZ [126]

The length of AB will be 10 units. Option B is corect. The formula for the distance between the two points is applied in a given problem.

<h3>What is the distance between the two points?</h3>

The length of the line segment connecting two places is the distance between them.

The distance between two places is always positive, and equal-length segments are referred to as congruent segments.

The given coordinate in the problem is;

(x₁,y₁)=(-2,-4)

(x₂, y₂)= (-8, 4)

The distance between the two points is found as;

$\rm d= \sqrt{(-8-(-2))^2+(4-(-4))^2}\\\\ d=10 \ units$
