Answer:
Angle CED must also measure 60°.
Because angle m is shown to be congruent to angles ABC and CDE, this means that angle m has a measure of 60 degrees.
There can only be 180 degrees in a triangle, so the measure of angle ACB must be 180-60-60, which equals 60 degrees.
Using the Vertical Angles Theorem, the measure of angle ACB is the same as the measure of angle CED.
Therefore, angle CED measures 60°.
Step-by-step explanation:
m, because Triangle ABC is similar to triangle EDC
m over 2, because Triangle ABC is congruent to triangle DCE
m + 60 degrees, because Triangle ABC is similar to triangle DCE
120 degrees − m, because Triangle ABC is congruent to triangle DCE
Answer:
a) They have different wavelengths.
b) They have different frequencies.
Step-by-step explanation:
Electromagnetic waves (EM waves) refer to waves carrying electromagnetic radiant energy which are propagated through vacuum or non-vacuum (material medium). They range from radio waves to gamma rays; they travel through space at the speed of light (about 300 million metres per second) and they are measured in photons.
The EM waves have the following characteristics:
1. They have different wavelengths
2. They have different frequencies
3. They travel at the speed of light independent of the medium of propagation (vacuum or material medium)
4. They do not require a media to be propagated
<u>Based on the explanation above, Options </u><u>a</u><u> (They have different wavelengths) and </u><u>b</u><u> (They have different frequencies) are the correct answers</u>
Answer:
Solution (1, 4)
Step-by-step explanation:
x = y - 3
x + 3y = 13
Substitute x = y - 3 into x + 3y = 13
y - 3 + 3y = 13
4y - 3 = 3
4y =16
y = 4
Substitute y = 4 into x = y - 3
x = 4 - 3
x = 1
Solution (1, 4)
4 divided by 7
Remember a fraction is just a division problem
Answer:
there is no solution
Step-by-step explanation:
theres no solution becuase its impossible for a to have 2 different values; you see that 0.1 and 0.01 are not equal, therefore a can not be equal,, otherwise the equation would be false
