The value for y is 17.5°
The equation is
Sin (3y - 30°) = Cos (7y +50°)
<h3>What is Trigonometry ?</h3>
Trigonometry is the branch oh Mathematics which involve the study of right angles , its sides and trigonometric ratios.
the equation given in the question is
Sin (3y - 30°) = Cos (7y +50°)
cos(90 - 
) = sin
Therefore
sin(3y-30°) = sin( 90-(7y+50°)
Equating the terms
3y - 30 = 90-7y -50
4y = 90-50+30
4y = 120-50
4y = 70
y = 17.5
The value for y is 17.5°

Answer: 245 feet
Step-by-step explanation:
Given: The height of the rocket after t seconds is represented by the formula:
[Differentiate both sides w.r.t. t]
Put
Also, 
i.e. height is maximum at t=7.
Maximum height = 
Hence, the maximum height the rocket reaches = 245 feet.
Answer:
Both are false
Step-by-step explanation:
B is 3 units below P
After dilation B' will be 5 units below P so cannot be on the same horizontal line.
similarly segment CD is 3 units long,
After dilation segment C'D' will be 5 units long so is not equal to segment CD.
