AB is the angle bisector of ∠CAD. Solve for x.
Sliva [168]

Answer: x=7

Step-by-step explanation:

Since AB is a bisector, it cuts the angle in half, and since we know that the angle is a right angle, we know it’s 90 degrees, so knowing that you use the equation 7x-4= 45 (since 45 is half of 90), add 4 to both sides so you have 7x=49, the divide 49 by 7 and you get 7, so x= 7

Is 50 a perfect square ? Explain your answer please 
xeze [42]
No, 50 is not a perfect square.  A perfect square is any number that can be divided by any number to get the quotient as the same number AND the quotient must be rational.  When you divide 50 so that the quotient equals the divisor, you will get an irrational number.  Therefore, 50 is not a perfect square.
