Answer:
Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
<u>45°-45°-90° triangle</u>
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
<u>30°-60°-90° triangle</u>
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36
(3)(-2.5) + (-8y)(-2.5) I think lol
The shaded squares are positive because a negative number multiplied or divided by a negative number makes the product or quotient positive. There is no specific rule that comes to mind, but if your teacher has provided a list of specific rules I would look for something mentioning negative numbers.
700,000 is the value of the digit
<span>Determine the x- and y-intercepts of each line x+3y=24
+ x=0, so y= 24:3=8 and we have </span><span>y-intercepts is 8
</span>+ y=0, so we have x=24, x<span>-intercepts is 24
Have fun</span>
