Answer:
The Pythagorean theorem should help you out. Since you already know two sides of the triangle, you can do a^2 + b^2 = c^2
So in this problem, 16.5^2 + 9.2^2 =
272.25 + 84.64 = 356.89
Pasty you would take the square root of 356.89 and you would get x = 18.89 or 18.9 rounded to the nearest tenth
You can check your work by the Pythagorean theorem once more. 16.5^2 + 9.2^2 = 18.9^2 and you should get the same approximate answer (it will be a little bigger because you rounded)
Answer:
Option B. 7/11
Step-by-step explanation:
The following data were obtained from the question:
Sin x = 7/11
Cos(90 – x) =..?
The value of Cos(90 – x) can simply be obtained as follow:
Recall:
Sin x = Cos(90 – x)
Sin x = 7/11
7/11 = Cos(90 – x)
Therefore, the value of Cos(90 – x) is simply 7/11.

Step-by-step explanation:
_ _ _ _
4 optional for every digit
4×4×4×4 = 256
Lo siento pero no entiendo inglés suerte con tú pregunta 8)
{ 0 x ≤ 5
f(x) = { 5 6 ≤ x < 18
{ 8 x ≥ 18
The brackets should be one big bracket.
