Answer:
21 degrees
Step-by-step explanation:
To find this, we are going to use the appropriate trigonometric ratio
The right angle faces the length 22 which is the hypotenuse
The marked angle faces the length 8 which makes it the opposite
The trigonometric ratio that links the two is the sine
The sine is the ratio of the opposite to the hypotenuse
So, we have it that;
sine ? = 8/22
? = arc sine 8/22
? = 21 degrees
Answer:
T = 3
Step-by-step explanation:
To find the period, find the distance it takes to complete one cycle.
7 because all the room contain 1//2 and Brandon has 7/1/2 i t pretty easy <span />
16 1/2 is the answer
6 1/2 is equal to 6 2/4 so 6 2/4 + 4 3/4 equals 11 1/4 plus 5 1/4 equals 16 1/2
Given a point on the xy-plane, a refrection across the y axis will change the sign of the x-value of the point.
For example, given a point (x, y) on the xy-plane, a refrection across the y-axis will transform the point to (-x, y)
Thus, give a triangle ABC <span>with vertices A(–3, 5), B(–2, 2), and C(–4, 3), reflected across the y-axis, the image of the triangle will have vertices which will have the signs on the x-values of the original triangle changed.
Thus, the vertices of the image will be A'(3, 5), B'(2, 2), and C'(4, 3).
Therefore, given that a student determined one of the vertices on the image to be (2, 2). It can be seen that the student performed the refrection correctly.
