<u>Trigonometric Ratios</u>
In every right triangle (those who have an internal angle of 90°), the six trigonometric ratios are valid. They relate the other internal angles with the lengths of the triangle.
The skateboard, the wall, and the ground form a right triangle. We need to find the measure of the angle formed by the skateboard with the ground. Let's call it β. In a right triangle, the cosine of an angle is defined as
The adjacent leg of β is the side with length 8 in, and the hypotenuse is the length of the skateboard, 30 in, thus:
Using a digital calculator we find:
Correct choice: C. 74.5
Answer: 44%
Step-by-step explanation: First, let's add up all the children in the classroom...
15 + 12 = 27
There's 15 boys, therefore have to divide 15 by 27...
15 ÷ 27 = 0.55 x 100 = 55%
Now, let's divided the total amount of girls...
12 ÷ 27 = 0.44 x 100 = 44%
44 + 55 = 99%
The perecent of girls in the classroom are 44%, I hope this helps!
<h3>
Answer:</h3>
y = -1/2x +(4 1/2)
<h3>
Step-by-step explanation:</h3>
The two marked points (-1, 5) and (1, 4) differ in y-value by -1 and x-value by +2, so the slope is -1/2.
The y-intercept is halfway between the marked y-values, so is at 4 1/2.
Putting these numbers into the slope-intercept form of the equation for a line, ...
... y = mx + b . . . . for slope m and y-intercept b
we have ...
... y = -1/2x +(4 1/2)
