<u>ΔACB</u> <u>ΔCDA</u>
AC² + BC² = AB² AD² + CD² = AC²
BC² = AB² - AC² BC² + CD² = AC² (AD=BC is given)
BC² = AC² - CD²
AB² - AC² = AC² - CD² (both sides were = to BC²)
AB² + CD² = 2AC²
(3)² + (√2)² = 2AC² (AB=3 and CD=√2 were given)
9 + 2 = 2AC²
11 = 2AC²
= AC²
= AC
= AC
A positive times a negative will always be negative
9 x -1 = -9
-9, Hope this helps!
Answer:
$145.50
Step-by-step explanation:
C = 45.50 + 2n
45.50 + 2X 100 = $145.50
Answer: Quotient means when you divided a number by another number.
Our first number will be 48 and also in this problem lets have that second "number" be x.
So 48/x is the quotient.
The length of the diagonal should be 18 if I am not wrong!
Step-by-step explanation:
a2+ b2=c2
so 10x10+15x15=the diagonal
100+225=325
325 squared = 18
