Answer:

The measure of angle DAC is 53 degrees.

Step-by-step explanation:

To solve for the measure of angle DAC,  start by realizing that the total measure of angle DAB is 90 degrees. The total measure of angle DAB is 90 degrees because there is a 90 degree box symbol representing angle DAB.

Now that the overall measure of angle DAB is known, we can look at the question, which says that the measure of angle CAB is 37 degrees. By knowing one of the angles in the total 90 degree angle, angle DAC can be found.

To find by the measure of angle DAC, start by writing an equation. The equation will look like:

the measure of angle DAC + the measure of angle CAB = the measure of angle DAB

Next, fill the equation in with the information given from the problem. The measure of angle DAC will be given the variable (x) since the measure of the angle is unknown. The equation will look like x+ 37 degrees= 90 degrees.

To solve the equation, subtract 37 degrees from both sides to get x by itself. Then, simplify the equation, and the final answer will be 53 degrees.

The measure of angle DAC is 53 degrees.

Identify the linear term in the function of y = 2x2 − 5x − 12
MakcuM [25]

Answer:

The linear term is -5x

Step-by-step explanation:

The linear term is the term that has the degree equal to 1.

The given function is

y = 2x^2 − 5x − 12

here 2x^2 = quadratic term i.e having degree 2

-5x = linear term i.e having degree 1

-12 = constant

so, The linear term is -5x

I need some help on this math problem, thanks so much
bekas [8.4K]

Answer:

The answer is C.

Step-by-step explanation:

Hit 'em with the Law of Sines.

sin(A)/a = sin(B)/b.

Let's say x is equal to "A", thus 5 is "a".

sin(x)/5 = sin(B)/b.

We could go for the obvious choice for "B", which would be the 90 degrees shown. To solve for the hypotenuse which will be "b", let's use the Pythagorean Theorem:

a^2 + b^2 = c^2

5^2 + 20^2 = c^2

25 + 400 = 425

sqrt(425) = about 20.6, which we can now substitute "b" with.

sin(x)/5 = sin(90)/20.6

sin(x)/5 = 1/20.6

sin(x)/5 = 0.04854...

sin(x) = 0.2427...

You can plug in sin^-1(0.2427) into your calculator, and you should end up with something like 14.047... which equates to answer choice C.

The angle next to the angle 5x is 180 - 5x

All angles sum to 360

(6x - 58) + (2x + 4) + (180 - 5x) = 180
3x + 126 = 180
3x = 54
x = 18

For question 10, sum of angles in pentagon is 540 degrees

x + 105 + 85 + 114 + 126 = 540
x + 430 = 540
x = 110
