Answer:
A
Step-by-step explanation:
Which segment shows what happens when x>2? What happens when x = 2 and which line shows it best. Which question is easier to answer?
It's not C or D.
Look at A. If x = 2 then -x + 4 = -2 + 4 = 2. I admit you can't let it be that way, but it gives you an indication of what to do. That is what happens to the short line on the right.
What is the long line doing? -2(2) - 1 = -5. Who does that? A does
So the Answer is A
If you want to find the length of other leg (AB) you can use Pythagoras
So, the length of other leg is 4√3 cm.
The acute angles are <B and <C (look at my drawing)
sin <B = 8/4= 1/2
<B = 30°
<C = 180°-(30+90)
= 60°
Hope this help!
