Α-(α-90°)=(α-180°)-α Pls help!

1 answer:

6 0

90=(a-180)-a 90=-180 That result is not possible so the answer should be undefined. If I am wrong and there is a solution, you can find it by Google searching a graphing calculator and then put the two equations y=x-(x-90) and y=(x-180)-x into the calculator. The x value for where the two equations intersect is the a value you are looking for. If the graphs never intersect, there is no solution like what my work shows. I hope this helps.

First, find the scale factor.

8.4 / 7 = 1.2

9 / 7.5 = 1.2

7.2 / 6 = 1.2

Since both solids are different sizes, the solids aren't congruent.

The size ratio for all the sides are:

8.4:7

9:7.5

7.2:6

Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent.

Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.

Best of Luck!

A piece of tile is 4 1/2 inches long and 3 1/4 inches wide. What is the area of the tile? A. 7 3/4 square inches B. 12 square in

First change the 4 $\frac{1}{2}$ to 4 $\frac{2}{4}$ .
Then multiply 4 $\frac{2}{4}$ and 3 $\frac{1}{4}$
The answer would be D) or 14 $\frac{5}{8}$ in².
