Answer:
Assume ΔABC is an acute triangle.
Step-by-step explanation:
Given the triangle ABC.
We have to tell the first step of indirect proving ΔABC is not an acute triangle.
An indirect proof, also known a proof by contradiction. When we use indirect proof method, we assume the opposite of our theory to be true and then by applying our assumed theory we contradict the given statement which proves our supposition is wrong. In other words, we assume our theory is false.
Hence, our first step is to
Assume ΔABC is an acute triangle.
Third option is correct.
Answer:
320
Step-by-step explanation:
5, 20, 80,5,20,80,5, comma, 20, comma, 80, comma is not a geometric sequence.
However, if you mean 5, 20, 80 it is a geometric sequence.
It is being multiplyed by 4 each time
so 80*4=320
The next number would be 320.

In order for a triangle to exist, the two smaller sides must add to a number greater than the largest side.
So, 13+10 = 23
So, the number has to be smaller than 23, and the largest whole number less than 23 is 22.
22 Is the largest possible whole number.
