7 cos x+1=6 secx solve for x

Mathematics
1 answer:
jonny [76]3 years ago
6 0
7cos(x) + 1 = 6sec(x)
7cos(x) + 1 = 6/cos(x)
7cos^(x) + cos(x) = 6
7cos^(x) + cos(x) - 6 = 0
[7cos(x) - 6][cos(x) + 1] = 0
cos(x) = 6/7 , x = arccos(6/7) and
cos(x) = -1, x = 180

What are the possible side lengths of a triangle
alina1380 [7]
1. Consider a triangle with sides a, b and c.

2. a, b and c can be sides of a triangle only if each of these conditions hold:

         i)  a+b>c
         ii) b+c>a
and   iii)a+c>b

3. So the only condition for 3 numbers to be the side lengths of a triangle is that the sum of any 2 of them must be larger than the third number

4. This is called the "triangle inequality".

Solve help please, thanks.
natka813 [3]

Answer:

2 √2 would be your answer.

Step-by-step explanation:

= √8y/√y

Both roots will be cancelled out,

= 8y/y

= 8

Factorising 8, we get

= 2√2
