A protractor is used to measure an angle. One ray points to 0° and the other ray points to 125° and 75°. What is the measure of

the angle if we know it is an acute angle?

It would be 75° because we know it is an acute angle, and an acute angle is an angle less than 90°

Step-by-step explanation:

Since a function would mean that a customer is able to purchase 1.1 of an item or 1.5 of an item, which is false. It also means that the customers pay the same price for a different amount of items.

Ulleksa [173]

Answer:

commutative property of multiplication

Step-by-step explanation:

The commutative property of multiplication is correct. The commutative property of multiplication is basically arranging the numbers in any way and it won't change the product.

The associative property of multiplication is arranging the numbers in parenthesis and it won't change the product either.

BD bisects m m Find m

The text of the question is not visible in the answering window. I'll reproduce it here:

BD bisects <ABC.

m <ABD= 2.5x + 8.6

m<CBD = 3.5x - 3.4

Find m<ABC

Answer:

$m\angle ABC = 77.2^\circ$

Step-by-step explanation:

We have an angle ABC and a line BD bisecting it.

If an angle is bisected, then the two formed angles are congruent, that is

$m\angle ABD=m\angle CBD$

Substituting the algebraic expressions for both angles:

$2.5x + 8.6=3.5x - 3.4$

Subtracting 8.6 and 3.5x:

$2.5x - 3.5x = -8.6 - 3.4$

Operating:

$-x = -12$

$x = 12$

The two angles are:

$m\angle ABD=2.5x + 8.6=2.5(12) + 8.6=38.6^\circ$

$m\angle CBD=3.5x - 3.4 = 38.6^\circ$

As expected, both angles have the same measure.

The measure of the total angle ABC is twice any of those:

$m\angle ABC = 2*38.6^\circ=77.2^\circ$

$\mathbf{m\angle ABC = 77.2^\circ}$

PLEASE HELP!!! I DONT HAVE ENOUGH POINTS TO POST MORE THAN ONCE!

Marat540 [252]

Answer:

-3.

Step-by-step explanation:

In the table, the y value goes down by -4 and then -2, for a total of -6.

We did this over a period of two units (To go from -1 to 1, we add 2).

-6/2 = -3.

-3 is the average rate of change over the interval.
