Answer:
Step-by-step explanation:
For this triangle we have to
We want to find the length of b
We know that the sum of the internal angles of a triangle is 180 °
So
Now we use the sine theorem to find the length of b:
Then:
Answer:
Step-by-step explanation:
<u>The line has a positive slope and negative y-intercept.</u>
This is only matched by a choice C
Answer: The correct answer will be C. (Since the last comment got deleted smh)
Right triangles must follow the pythagorean theorem, so a^2+b^2=c^2.
Let's find a^2 and b^2 by squaring the first 2 side lengths.
(x^2-1)^2= x^4-2x^2+1
(2x)^2= 4x^2
Then add the two to find c^2
x^4+ 2x^2 +1= c^2
Root both sides
x^2+1=c
Since the side lengths can be plugged into the pythagorean theorem, the side lengths must represent a right triangle.
Hope this helps!
If there are 5 specific spots and the order does matters then we would have:
11*9*8=792
Hope this helps!
