<span>Cosine and Sine are related by the formula cos(x)= sin(x+90). Setting x+90 equal to 75 results in x=-15, Therefore, cos(-15) = sin (75). Since cos is an even function, cos(15)=cos(-15)= sin(75).</span>
Answer:
The measure of a minor arc is less than 180° , and equal to the measure of the arc's central angle . A major arc is the longer arc connecting two endpoints on a circle. The measure of a major arc is greater than 180° , and equal to 360° minus the measure of the minor arc with the same endpoints.
Answer:
V ≈3769.91
explanation:
V = π r 2h = π·10^2·12 ≈3769.91118 in³
Answer:
The value of x is 13
Step-by-step explanation:
To solve this, we create a proportion. First create two fractions that compare corresponding sides.
2/8 = 2.5/x - 3
Now cross multiply to solve for x.
8 * 2.5 = 2(x - 3)
20 = 2x - 6
26 = 2x
13 = x
Thhe graph of a linear relationship will be a straight line.
Non linear would be a curve.
