Answer:

<h2>79.2°</h2>

Step-by-step explanation:

We know,

That Angle 1 and angle 3 are vertically opposite angles.

And as vertically opposite angles are always equal so

<h3>According to the question</h3>

13x + 22 = 18x

=  > 22 = 18x - 13x

=  > 5x= 22

=  > x =  \frac{22}{5}

=  > x = 4.4

Now,

We know that the value of x is 4.4°

And Angle 3 = 18x

So,

angle \: 3 = 18x

=  > angle \: 3 = 18(4.4)

=  > angle \: 3 = 79.2

___________________________________

We can even Check it!!

We know that Angle 1 = Angle 3 ( Vertically opposite angles)

So,

<h3>According to the question</h3>

13x + 22 = 18x

=>13(4.4) + 22 = 18(4.4)

=> 79.2 = 79.2

As L.H.S = R.H.S

So The measure of angle 3 is 79.2° ( and it is already rounded to the nearest tenths.)

Hope it helps you!!

Answer:

79.2°

Step-by-step explanation:

We know,

That Angle 1 and angle 3 are vertically opposite angles.

And as vertically opposite angles are always equal so

According to the question

13x + 22 = 18x13x+22=18x

= > 22 = 18x - 13x=>22=18x−13x

= > 5x= 22=>5x=22

= > x = \frac{22}{5}=>x=522

= > x = 4.4=>x=4.4

Now,

We know that the value of x is 4.4°

And Angle 3 = 18x

So,

angle \: 3 = 18xangle3=18x

= > angle \: 3 = 18(4.4)=>angle3=18(4.4)

= > angle \: 3 = 79.2=>angle3=79.2

= > 79.2 = 79.2=>79.2=79.2

As L.H.S = R.H.S

So The measure of angle 3 is 79.2° ( and it is already rounded to the nearest tenths.)

For ΔABC, ∠A = 2x - 2, ∠B = 2x + 2, and ∠C = 5x. If ΔABC undergoes a dilation by a scale factor of 1 2 to create ΔA'B'C' with ∠A
Zolol [24]
<h3>Answer:</h3>

A) ∠A = ∠A' = 38° and ∠B = ∠B' = 42°

<h3>Explanation:</h3>

The sum of angles in ∆ABC is 180°, so ...

... (2x -2) + (2x +2) + (5x) = 180

... 9x = 180

... x = 20

and the angles of ∆ABC are ∠A = 38°, ∠B = 42°, ∠C = 100°.

___

The sum of angles of ∆A'B'C' is 180°, so ...

... (58 -x) +(3x -18) +(120 -x) = 180

... x +160 = 180

... x = 20

and ∠A' = 38°, ∠B' = 42°, ∠C' = 100°.

_____

The values of angle measures of ∆ABC match those of ∆A'B'C', so we can conclude ...

... A) ∠A = ∠A' = 38° and ∠B = ∠B' = 42°

Choose the four expressions that are equivalent to 3^-4 ?
Ivan

3^(-4) means "one over 3^4"

    1/(3^4)

That's equal to

    1/81

and

    (1/3)^4

This is also equal to 3^2/3^6.  

So four of those are correct.
