Let
be the length of one leg, and
be the length of the hypothenuse. Finally, let
be the measure of the angle between them. Then, the following relation holds:

Plugging your values, we have

Solving for x, we have

<u>Answer</u>
1
<u>Explanation</u>
The general equation of a wave is ;
y = a sin(kX+Ф)
Where a represent the amplitude, 360/k represent the period of the wave and Ф represent the phase angle.
∴ In the equation y = 1 sin 2x,
Amplitude = 1
The function is invertible on either side of the vertex. There are many possible answers. Ones that include the vertex are ...
x ≥ 3
or
x ≤ 3

Explanation:
A)
Let t and f represent the numbers of two-point and four-point questions, respectively.
__
B) The number of points for each type of question is the product of the point-value per question and the number of questions of that type.
2t + 4f = 100 . . . . . the test is worth 100 points
t + f = 40 . . . . . . . . there are 40 questions on the test
_____
<em>Additional comment</em>
The test will have 30 two-point questions and 10 four-point questions.
