Answer:
I believe the answer to this question is: X= -3 3/4
Yes, 15 for both sides and 7 for the bottom. It will make an Acute Isosceles Triangle.
Answer:
120.51·cos(377t+4.80°)
Step-by-step explanation:
We can use the identity ...
sin(x) = cos(x -90°)
to transform the second waveform to ...
i₂(t) = 150cos(377t +50°)
Then ...
i(t) = i₁(t) -i₂(t) = 250cos(377t+30°) -150cos(377t+50°)
A suitable calculator finds the difference easily (see attached). It is approximately ...
i(t) = 120.51cos(377t+4.80°)
_____
The graph in the second attachment shows i(t) as calculated directly from the given sine/cosine functions (green) and using the result shown above (purple dotted). The two waveforms are identical.
Answer:
1,600
Step-by-step explanation:
Answer:
3k + 0 = 3k
Step-by-step explanation:
Identity property of addition states that the sum of 0 and the term would result in the term.
∴ in this case, 3k + 0 will result in 3k.
