Step-by-step explanation:
For the first one, in any triangle, we have the sum of two sides is greater than the third side. Hence, we have 3 inequalities: , which give us
. We conclude that
.
For the second question, we have , and similarly we can show that
. Hence,
.
The third question is not very clear.
Additive inverse is the number you add to a given number to make the sum zero. The addition of both the number must be zero to make both numbers additive inverse.. The additive inverse of the given complex number is
Addictive Inverse-Additive inverse is the number you add to a given number to make the sum zero. The addition of both the number must be zero to make both numbers additive inverse.
Let an example, if we take the number 10 and add -10 to it. Thus -10 is the additive inverse of the number 10.
Here, the given number is a complex number. A complex number is a number of the form a + bi, where a and b are real numbers. The given function is,
The additive inverse of the above number is,
Add both and check by equating with zero,
Hence, the additive inverse of the given complex number is .
