If you would like to evaluate A^2 for A = - 3, you can do this using the following step:
A^2 = (-3)^2= +9 = 9
If you would like to evaluate 2 * A for A = -3, you can do this like this:
2 * A = 2 * (-3) = -6
Answer:
Step-by-step explanation:
The two rectangles are similar and the scale factor is
30 feet tall since the other tree is 40 an only cast a 30 foot shadow just add ten to the other shadow
The supplementary angle to 69 degrees would be 111 DEGREES.
