Since there was a ray drawn from A through C the exterior angle of angle C is angle 1. Any straight line should equal to 180 degrees.
A=3.14(4)(4+sq rt of 3squared + 4 squared)
A=3.14 (4)(4+5)
A= 3.14 (4)(9)
A=113.04
Answer:
2.5 x 10^-7 m
Explanation:
We can substract the wavength of the violet light to the wavelength of the red light:
(6.5 x 10^-7 m) - (4.0 x 10^-7 m) = 2.5 x 10^-7 m
This is the difference between this two values of wavelength.
So the wavelength of red light is 2.5 x 10^-7 m longer than violet light.
Answer:
40 cm^2
Step-by-step explanation:
The area of the polygon is comprised of two triangles, each of which can be broken down into two right triangles for a total of four right triangles when split vertically.
The formula for the area of a triangle is: A = 1/2 * base * height.
The base for both triangles is 8 cm, and the height for both triangles is given on the right (6 cm for the top triangle and 4 cm for the bottom triangle).
The area of the top triangle will be:
A = 1/2 * 8 * 6
A = 4 * 6
A = 24
The area of the bottom triangle will be:
A = 1/2 * 8 * 4
A = 4 * 4
A = 16
Adding the values of the two areas, we get a total area of 40 cm^2.
Given that cos Ф = 5/6 I know that one side is 5 and the hypotenuse is 6 so the other side is:
a^2 = c^2 - b^2
a^2 = 6^2 - 5^2
a^2 = 36 - 25 = 11
a =
Now I know that the sin is
since sin is defined as opposite/hypotenuse
the second one uses a form of C = pi * d we are going to add the sector part to it.
C = 6 and the central angle is 4 degrees we can set up like this:
d = 171.974
r = 171.94/2 =85.987
