Answer:
First you can just flip the line on point C to make a 90 degree angle. That's the simple way.
Other way is to get the slope of AB let's say ex : -1/2
We need to get the slope of C to be a reversed reciprocal of -1/2. So, 2.
Basically I flipped -1/2 in to -2/1 then removed the negative sign for 2.

Answer:
30
Step-by-step explanation:
The absolute value function always gives a positive value, that is
| - a | = | a | = a
Given
| - 10 | + | - 20 |
= 10 + 20
= 30
Answer:
39 athletes
Step-by-step explanation:
There is a total of 45 people on the bus. This INCLUDES the athletes (A), 2 coaches and 4 managers.
Therefore, we need to sum A, 2 and 4 and equal it to 45:
2 + 4 + A = 45 so we need to used equation d.
To calculate how many athletes are on the bus, find the value of A:
2 + 4 + A = 45
Subtract 2 from both sides: 4 + A = 43
Subtract 4 from both sides: A = 39
