One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
How many tiles do they have?
36*24=864 If the amount of tiles they have is less than 864, subtract 864 by the amount of tiles.
If looking for the answer it would be 0, 3, -6, 7
The answer is C because you just have to plug in the given point to the different answers.
