√B and √C are supplementary angles.
√B + √C = 180
4x + 60 = 180
4x = 120
x = 30
Answer: A
Answer:
2.6549
Step-by-step explanation:
Since the sample size n=65, the degrees of freedom is n-1=65-1=64
The critical value=
Using the t-table and selecting df=64 and
since it’s a 2 tail the corresponding t-score is 2.6549
Therefore, the critical value is 2.6549
Answer:
rotation 90° CW about the origin we defined
Step-by-step explanation:
The image has the same orientation (clockwise order of vertices) as the pre-image, so an even number of reflections is involved. These cannot be reflections across the x- or y-axes. The longest edge has an east-west orientation in the pre-image and a south-north orientation in the image. Any reflections must have a net effect of a rotation 90° CW.
Equivalently, the image is rotated 90° clockwise from the pre-image.
With a suitable choice of center of rotation, the image can be obtained with a single 90° CW rotation transformation.
If we define the lower left corner of the pre-image as having coordinates (-1, 2), then a 90° CW rotation about (0, 0) will yield the image.

Answer: 665.68 ft
Step-by-step explanation:
You‘re trying to find the circumference of the Ferris wheel. The formula for circumference is C=3.14(approximation for pi)x the diameter. So you would do 3.14 x 212 = 665.68
