Answer:
11.6 cm
Step-by-step explanation:
As the page title tells you, the Pythagorean theorem must be applied more than once. As you know, it tells you the square of the hypotenuse is the sum of the squares of the two sides.
AD² = ED² +EA²
EA² = AD²-ED² = 7² -6² = 13
EA = √13 ≈ 3.606
__
CD² = ED² +EC²
EC² = CD² -ED² = 10² -6² = 64
EC = √64 = 8
__
The length of the horizontal diagonal is ...
AC = EA +EC = 3.6 +8 = 11.6 . . . cm
An example of a ratio would be:
1:2
3:4
5:6
An example of a proportion would be:
1/2
3/4
5/6
Hope this helps!
I think it might be 11/12 you can enter it into a smart calculator that's what I did hope this helps
99.60 or 100.00? I haven’t done this for a longgggg time
To find a perpendicular line, you need to find the negative reciprocal of the slope.
-2/5 flips into -5/2
Since -2/5 is negative, -5/2 turns positive, so 5/2.
Therefore, the slope of a line perpendicular to Y = -2/5x + 4/5 is 5/2
