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!
Angle UTV is basically given: it's 138°.
Moreover, since UTV is isosceles, the other two angles have the same measure x. We thus have

So, TUV is 21°, and VUW is complementary, so it must be 69° so that they sum up to 90°
The answer would be $152.20 because 132*1.153=152.196, rounded to $152.20.
Answer:
(2x-8)(2x+8)
4x squared -64 is the answer
how you get it is by multiplying 2x times 2x to get 4x squared and -8 times 8 = -64
hope this helps
if this is algebra 1 then this is right
Answer:
(i think this is wh ast your asking for)
x = 3
Step-by-step explanation:
36 - 12x = 0
- 12x = -36
x = 3
