Answer 1
The answer is 39 because the measurement of CBA is 90 so if CBD is 51 then u have to take away 51 out of 90
Answer 2

Answer: 39°

Step-by-step explanation:

This is a right triangle, meaning one of the angles is a 90° angle. Angle CBA in this case is the 90° angle. In order to figure out the measure of ABD, you subtract the measure of CBA by the measure of CBD, which is 51°.

90 - 51 = 39

Thus, the measure of ABD is 39°

Answers

Answer:

29 degrees

Step-by-step explanation:

Given

<D = 2x+8

<A = 122

The sum of the adjacent angle of the trapezoid is 180 degrees

<D + <A = 180

2x + 122 = 180

2x = 180-122

2x = 58

x = 58/2

x = 29 degrees

Hence the value of x is 29 degrees

Answers

Answer:

Yes it is true. Sum of two integers is always an integer

Step-by-step explanation:

Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

Answer:

[tex]sin 40 = \frac{x}{11}[/tex]

Step-by-step explanation:

[tex]sine = \frac{opposite}{hypotenuse}[/tex]

Side x is the opposite, since it is opposite the angle you are solving for.

Side y is the adjacent, since it is next to the angle you are solving for.

The side measuring 11 is the hypotenuse, since it is across from the right angle.

A teacher wrote a question on the board to which
42.5
%
of the
40
students in her class could not give the correct answer.

What is the number of students who answered correctly?


Answers

Answer:

23

Step-by-step explanation:

find 10% = 4

quadruple it = 16

half 10% = 2

half it again = 1

2.5% = 1

40% = 16

1 + 16 = 17

take 17 off of 40 = 23

100% - 42.5% = 57.5%
57.5% of the 40 students answered correctly.
57.5% of 40 = 0.575 × 40 = 23 students

Step-by-step explanation:

Notice that the x-coordinate remains the same, 7, for both points, whereas the y-coordinate changes.  Thus, the line through these two points is a vertical one:  x = 7.  No, this is not a function, since one x value (7) has more than one y values associated with it.

use the change flip method due to divide

Answer:

See step-by-step explanation.

Step-by-step explanation:

When dividing a fraction it is not actually dividing, it is more multiplying.

Our sum looks like this:

3/5 ÷ 1/3

The method here is to flip the second fraction and change the divide sign into a multiplication sign. Here is what is looks like step-by-step.

3/5 ÷ 1/3

3/5 ÷ 3/1

3/5 × 3/1

Now we can finish the sum off by multiplying across.

3 × 3 = 9

5 × 1 = 5

9/5, this is a top-heavy fraction.

If we want it as a mixed fraction then here it is:

1 4/5 (that is one and four fifths).
