Answer:

Step-by-step explanation:


Let's solve for
in the first equation and then solve for
in the second equation.
I will then use the following identity to get right of the parameter,
:
(Pythagorean Identity).
Let's begin with
.
Subtract 2 on both sides:

Divide both sides by -3:

Now time for the second equation,
.
Subtract 1 on both sides:

Divide both sides by 4:

Now let's plug it into our Pythagorean Identity:




Answer:
Steps below
Step-by-step explanation:
The value depends on which angle is B, suppose ∠B is the opposite angle of side length 7
sin B = 7/25
cos B = 24/25
tan B = 7/24
if ∠B opposite to side length of 24
sin B = 24/25
cos B = 7/25
tan B = 24/7
If it's 4 less than 2 times a number if would be

I think the answer is -1=x-3<4
