Answer:
1)When subtract you will still get a negative number
Answer:
the answer would be 9 I think
Answer:
60 degrees
Step-by-step explanation:
A triangle adds up to 180 degrees. 180 divided by 3 is 60. The answer is 60 degrees.
A system of equation may have one, zero or infinitely many solutions
The system of equation has no solutions
The systems of equation are given as:
Substitute -6x - 5 for y in
Open brackets
Subtract 12x from both sides of the equation
The above equation is not true i.e.
Hence, the system of equation has no solutions

Its a right angled triangle. You have C and have B all you need to find is A. usually for a question like this you would use the Pythagorean theorem which is A2+B2=C2 but since we already have c we will use C2-B2=A2
Now we fill in the values. (21)2-(9)2=A2
441-81=360^2 so now with the 360^2 we have to squareroot it so the square root of 360 is 18.973f
