The figure is the right triangle DEF.
In it, E is the 90° angle, D is the corner over E (this is, DE is the vertical segment or height from the base) and F is the corner to the right of E (f, is the angle and EF is the horizontal segment or base of the triangle).
Then EF is the adjacent leg to the angle f, DE is the opposite leg to the angle f, and DF is the hypotenuse of the triangle.
Given that the angle f is 45°, you know that the triangle is isosceles (45-45-90) and then the two legs have the same length and you can use Pytagorean theorem:
DF^2 = x^2 + x^2 = 2x^2 => x^2 = (DF)^2 / 2
Taking square roots from both sides:
=> x = DF / √2 = 22 / √2 = [22√2] / [(√2)(√2)] = [22√2] / 2 = 11√2
Remember, both legs have the same length.
Answer: 11√2
Answer:
1
Step-by-step explanation:
Calculation steps:
-7-(-8) = ⇒ two negatives cancel and change to positive
- 7 + 8 = ⇒ 8-7 = 1
1 ⇒ answer
Answer:
the answer would be B I believe
Multiply 8 the numerator and denominator to the second one.
12/1
8(12/1)
96/8
Now they have the same denominators.
Answer:
Graph g(x) = 2x - 3
Step-by-step explanation:
Plug in (x+1) to f(x) = 2x - 5:
g(x) = 2(x+1) - 5 = 2x + 2 - 5
g(x) = 2x - 3
