Answer:
MY friend the anwser is A I hope this will help plz mark me brainliest
Step-by-step explanation:
<span>So, x+15 + 2x = 90 </span><span>
<span>Therefore 3x = 90 - 15 = 75 </span>
<span>and so x=25. </span>
<span>So the smaller angles are x+15 = 40 degrees and
2x=50 degrees. </span>
<span>So the larger one is 50 degrees.</span></span>

Answer:
(A) 
Step-by-step explanation:
Given:
Frequency of the wave (f) = 
Speed of the wave (v) = 
The wavelength equation of the wave is given as:
Here, 
Now, plug in the given values and simplify.
Therefore, the wavelength of the wave is option (A)
Answer:
u ≤ 4
Step-by-step explanation:
The given inequality
15 ≤ 39 - 6u
Subtract 39 from both sides, we get
15 - 39 ≤ 39 - 6u - 39
-24 ≤ -6u
Dividing both sides by -6, we get
4 ≥ u [Remember, when we divide by negative, the direction of
the inequality changes]
Which is u ≤ 4.
Thank you.
