Answer:
Angle BAC: 56
ANGLE BCA: 42
Why? First find angle BCA because that angle is on a straight line with another angle on the other side you can do
180-138=42 which is the measurement of angle BCA.
For angle BAC you have to know that the sun of all triangles interior angles is 180 so you do
180-82-42=56
So angle BAC is 56

Answer:
(0,-5)
Step-by-step explanation:
You just have to find the middle of each one
From -8 to 8 there are 16 numbers so you divide 16 by 2 which would be 8 and add that to -8 giving you 0
From -10 to 0 there are 10 numbers divided by 2 is 5 so you add 5 to -10 giving you -5
This makes your midpoint (0,-5)
The answer is: -3y+9z
This is because you simply switch the sign for every number in the parentheses.
Hope this helps!
