a) On string number one, we know the angle created with string number three is 135 degrees. What is the measurement of angle A? Explain or defend your answer.
 The measure of angle A in this case will be given by the following mathematical relationship:
 135 + A = 180
 So we have to clear A:
 A = 180-135
 A = 45
 Answer: 
 the measurement of angle A is:
 A = 45 degrees
 b) What is the measurement of angle B? Explain or defend your answer.

 The angle B in this case, we observe that it is an angle opposite by the vertical at the angle of 135 degrees. We then have that by opposite angles with respect to line 3, then:
 B = 135 degrees
 Answer: 
 the measurement of angle B is:
 B = 135 degrees

 c) If Roger has created his tennis racket according to plan, what should be the measurement of angle C? Explain or defend your answer.

 As lines 1 and 2 are parallel lines, then we have that in this case the angles formed by both lines with respect to line 3 are the same.
 Therefore we have:
 C = A = 45 degrees
 Answer:
 the measurement of angle C should be:
 C = A = 45 degrees

Answer: x= 21.6

Step-by-step explanation:

12^2  + 18^2  =x^2

144 + 324 =x^2

468  = x^2

c=  21.633

Find one positive angle and one negative angle that are coterminal with the given angle. Explain.
Setler [38]

Answer: 10) 615° & -105°

               12) -440° & 280°

<u>Step-by-step explanation:</u>

Coterminal means it is in the exact same spot on the Unit Circle but one <em>or more </em>rotations clockwise <em>or counterclockwise.</em>

Since one rotation = 360°, add or subtract that from the given angle until you get a positive <em>or negative</em> number.

10) 255° + 360° = 615°     (this is a POSITIVE coterminal angle to 255°)

     255° - 360° = -105°     (this is a Negative coterminal angle to 255°)

12) -800° + 360° = -440°   (this is a Negative coterminal angle to -800°)

    -440° + 360° =  -80°      (this is a Negative coterminal angle to -800°)

      -80° + 360° = 280°     (this is a POSITIVE coterminal angle to -800°)

Charlie made the following table to record the height of each person in his family.
IRISSAK [1]

Answer:

4

Step-by-step explanation:

Since the question does not specify if you are rounding up or down, just round down to four from 4 1/6. 4 1/6 is closer to 4 than it is to 4 3/6 or 4 1/2.

A function of the form f(x)=ab^x is modified so that the b value remains the same but the a value is increased by 2. How do the
ANEK [815]

Answer:

The domain and range remain the same.

Step-by-step explanation:

Hi there!

First, we must determine what increasing <em>a</em> by 2 really does to the exponential function.

In f(x)=ab^x, <em>a</em> represents the initial value (y-intercept) of the function while <em>b</em> represents the common ratio for each consecutive value of f(x).

Increasing <em>a</em> by 2 means moving the y-intercept of the function up by 2. If the original function contained the point (0,x), the new function would contain the point (0,x+2).

The domain remains the same; it is still the set of all real x-values. This is true for any exponential function, regardless of any transformations.

The range remains the same as well; for the original function, it would have been y\neq 0. Because increasing <em>a</em> by 2 does not move the entire function up or down, the range remains the same.

I hope this helps!
