Answer:
56
Step-by-step explanation:
You subtract how long the shadow is from how long it is from the tree. This is true because the shadow is shorter than the tree because of the sun's ability to create it
Answer:
20
Step-by-step explanation:
which side is x ? the Hypotenuse - the side opposite of the 90 degree angle ? or is it one side touching the 90 degree angle ?
that is important. we need to know which side is the Hypotenuse to make the right calculations.
if I assume x is the Hypotenuse, then the calculation follows Pythagoras like this
x² = 12² + 16² = 144 + 256 = 400
x = sqrt(400) = 20
but just in case, if x is a side touching the 90 degrees angle, then the would look like this (depending on which of the other sides is the Hypotenuse)
either
12² = 16² + x²
144 = 256 + x²
-112 = x²
that did not work. a square root of a negative number did not work for actual distances.
or
16² = 12² + x²
256 = 144 + x²
112 = x²
x = sqrt(112) = 10.58
Answer:
1:5.8
Step-by-step explanation:
I think: Substitute what X would be for one then solve; do the same for if X was 5 then set up a ratio and simplify
Do the inverse operation on both sides
