Had to do a bit of guesswork to figure out what you're asking here. If you're given the 2 angles pi/4 and pi/6, you can find any trig function of either angle.
The sine of pi/4 is 1 / sqrt(2); the cosine is the same.
The cosine of pi/6 is sqrt(3) / 2; the sine of pi/6 is 1/2.
If this isn't quite what you were looking for, try paraphrasing your question to make it clearer.
Answer:
0.4 > 0.27
Step-by-step explanation:
0.4 is more if you look at the diagram
Answer:
A: 18x+15
Step-by-step explanation:
5(4x+3)-2x
Distribute the 5
20x +15 - 2x
Combine like terms
20x-2x +15
18x +15
Answer:
32
Step-by-step explanation:
If she started with 28, ad had 50 after she picked, you wold subtract 28 from 50 to find your answer.
The formula in computing the area of the circle is:
A = pi (r)^2
Where r = the radius of the circle
Since you are only given the diameter of the circle, you
have to solve for its radius. The radius of the circle is half its diameter. Therefore,
the radius of the circle is 5 (10/2).
Now, you substitute the measurements to the formula:
A = 3.14 (5)^2
A = 3.14 (25)
A = 78.5 sq. units
