Use the exponent property regarding a power to power. When you have a power to power, you multiply both powers. In this case, you will get 7^-6. That is equivalent to the first option. I hope this helped, though it is a bit late xD.

In triangle A B D , the measure of angle A is 10 degree less than the measure of angle B . The measure of angle D is 20 degree m

elixir [45]

Answer:

<u><em>Measure of angle A is 27 7/9 degrees.</em></u>

Step-by-step explanation:

Lets call measure of angle A is <em><u>X-10</u></em>

Lets call measure of angle B is X

Lets call measure of angle D is 2.5X+20

We know that the sum of triangles add up to 180 degrees

X+X-10+2.5X+20=180

X=37 7/9

So measure of angle A is 27 7/9 degrees.

I hope this is right. :)

Reflect the point (2, -4) over the y-axis. Question 1 options: (2, 4) (-2, -4) (-4, 2) (-2, 4) Question 2 will mark the brainlie

Answer:

The coordinates of the image point will be (-2,-4).

Step-by-step explanation:

The reflection of the point (2,-4) over the y-axis is to be determined.

Now, as the reflecting mirror is the y-axis, then the y-coordinate of the reflecting point will not change.

So, the image point will have coordinates (h,-4).

Now, after the reflection over the y-axis, the x-coordinate of the image point will change the sign only compared to the original point.

Therefore, the coordinates of the image point will be (-2,-4). (Answer)

The value of m is 2450

<h3>What is Equation?</h3>

Two or more expressions with an Equal sign is called as Equation.

The given equation is

2(14m/400)=171.5

Distribute 2 with numerator on LHS

28m/400=171.5

14m/200=171.5

7m/100=171.5

Multiply 100 on both sides

7m=17150

m=2450

Hence, the value of m is 2450
