Answer: 9 meters
Step-by-step explanation:
A line between two opposite corners splits the floor into two right angled triangles, therefore we can use Pythagoras’ Theorem which is:
a^2 + b^2 = c^2
where c is the hypotenuse, and a and b are the other two sides.
Hypotenuse in this question is 15 metres while one side is 12 metres. The length will now be:
12^2 + b^2 = 15^2
b^2 = 15^2 - 12^2
b^2 = 225 - 144
b^2 = 81
b = ✓81
b = 9m
The length of the storage unit is 9m
Answer:
-19/36
We can find the slope using
m = ( y2-y1)/(x2-x1)
m = ( 94-56)/( 28 -100)
= 38 / -72
= -19/36

CosC=0.99
Cos C =adjacent /Hypothenus
=36/45
=0.99
30
5(z+4)+5(2-z) (expand parentheses by distribution)
= z(5) + 4(5) + 2(5) -z(5)
= 5z + 20 + 10 -5z
= 30
