If two sides of a triangle are 1 and 3, the third side may be?
olya-2409 [2.1K]
Hello!

To solve this we can use the Pythagorean Theorem, a²+b²=c², where a and b represent the legs and c represents the hypotenuse. We will solve below.

1²+3²=c²
1+9=10

We have 10=c². We can isolate c by finding the square root of 10.

√10≈3.16

Therefore, the other side could be 3.16.
---------------------------------------
Note that 3 could also be the hypotenuse. We could solve the equation the other way around to see what the other side could be (it could be the hypotenuse or a leg).

9-1=8
√8≈2.83

Therefore, the length of the third side could be either 3.16 or 2.83.

I hope this helps!

What is the additive inverse of –2 8i? 2 8i –2 – 8i 2 – 8i –2 8i.
balandron [24]

The additive inverse of –2+ 8i will be 2 – 8i. The additive inverse of a digit is the digit that delivers zero when added to it.

<h3>What is additive inverse?</h3>

The additive inverse of a number is the number that produces zero when added to it. A negative number's additive inverse is positive. The additive inverse of itself is zero.

From the definition;

\rm x= 2+ 8i \\\\ \rm x= 2+ 8i + 2-8i \\\\ \rm x= 0

Option C gives zero on addition. That's why it is correct.

Hence the additive inverse of –2+ 8i will be 2 – 8i.
