Use the lengths of corresponding sides
so answer is 16:40 which simplifies to 2:5.
This is a classic example of a 45-45-90 triangle: it's a right triangle (one angle of 90) & two other sides of the same length, which means two angles of the same length (and 45 is the only number that will work). With a 45-45-90 triangle, the lengths of the legs are easy to determine:
45-45-90
1-1-sqrt2
Where the hypotenuse corresponds to sqrt2.
Now, your hypotenuse is 10.
To figure out what each leg is, divide 10/sqrt2 (because sqrt2/sqrt2 = 1, which is a leg length in the explanation above).
Problem: you can't divide by radicals. So, we'll have to rationalize the denominator:
(10•sqrt2)/(sqrt2•sqrt2)
This can be rewritten:
10sqrt2/sqrt(2•2)
=10sqrt2/sqrt4
=10sqrt2/2
=5sqrt2
Hope this helps!!
That would be D
the first 3 = -12x + 24
bur D = -12x - 24
Answer:
23.2
Step-by-step explanation:
Scaling down by a factor of 1/10 is equal to dividing the number by 10.
So 232 getting scaled down by a factor of 1/10 is equivalent to 232/10 i.e. 23.2.
Answer:
5+12
there is no equals sign in an expression so it is just that
