Answer:
B' = 105°
C = 27°
A = 48°
Step-by-step explanation:
Given
B = 105°
C = (2x - 3)°
C' = (5x - 48)°
Rotation = 90°
Before solving the requirements of this question, it should be noted that rotation do not change the angle of shapes.
i.e. an angle retain its measurements pre and after rotation.
Solving (a): The measurement of B'
Using the analysis above.
B' = B
Recall that
B = 105°
So:
B' = 105°
Solving (b): A and C
First, I'll solve for C.
Using the same analysis above.
C = C'
Substitute values for C and C'
5x - 48 = 2x - 3
Collect like terms
5x - 2x = 48 - 3
3x = 45
Multiply both sides by ⅓
⅓*3x = ⅓*45
x = 15
Substitute 15 for x in
C = (2x - 3)°
C = 2 * 15 - 3
C = 30 - 3
C = 27°
Solving for A
The sum of angles (A, B and C) is represented as:
A + B + C = 180
Substitute values for B and C
A + 105° + 27° = 180°
A + 132° = 180°
Collect like terms
A = 180° - 132°
A = 48°

Answer:
The domain is where is an integer.
Step-by-step explanation:
We see from the data given that the domain of T(a) takes both positive and negative integer values <em>( 8848 meters and -418 meters);</em> T(a) never gets decimal values<em> (and in real life thy won't be of much use because we are not looking for that much accuracy).</em>
So the appropriate <em>number type</em> for the domain of T(a) would be integers. And if you are interested, the domain is .
$550/people = price per person
550/25= $22 per person
550/50= $11 per person
550/55= $10 per person
3x + 2x = 5x
-3 - 8 = -11
5x - 11 = 0
5x - 11 (+11) = 0 (+11)
5x = 11
5x/5 = 11/5
x = 11/5
hope this helps
