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
Hope this helps :D
You can add the numbers together so:
12.6
3.1
<u>+ 5.4
</u> 21.1
<u>
</u>Since the sum of the numbers is 21.1, it is greater than 20<u>
</u>
The answer is 45
Explanation: if X=5 then we plug in x so now we get the equation 9 times 5 so the answer is 45 to check this we can divide 45 by 5 or 9 and we will see that the answer is correct have a nice day (: and a fortitude of a week
