Answer:
33.9915
Step-by-step explanation:
take 39.99 divide it by 20
then multiply by 3
then take off the original number
If a line is bisected by another, the 2 angles that make up the straight line will always add together for a total of 180 degrees. So the angle adjacent to the 137 degree angle will be
180 - 137 = 43 degrees.
All interior angles of a triangle add up to 180 degrees so now that we have another interior angles, we can find detailed the missing angle..
180 - 43 - 102 = 35 degrees
Now we find the adjacent able just like we did for the first angle..
180 - 35 = 145 degrees
Answer:
Electromagnetic waves have crests and troughs similar to those of ocean waves. The distance between crests is the wavelength. The shortest wavelengths are just fractions of the size of an atom, while the longest wavelengths scientists currently study can be larger than the diameter of our planet!
