Answer:
128.
Step-by-step explanation:
did all angles to find out x = 8. makes only sense. So exterior angle is 16x8 which is 128. if their is more to question whoops lol. if not ur welcome. pls rate if correct or not.
Answer:
angle SRT = 180 -44 = 136 °
Step-by-step explanation:
mark me as brainliest ❤️
Diagonals of a rectangle are congruent.
18x - 28 = x + 380
Solving for x, I get 17.
So, x = 17.
PR = 18x - 28
PR = 18(17) - 28
PR = 278
QS = x + 380
QS = 17 + 380
QS = 397
Answer:
The cosine function to model the height of a water particle above and below the mean water line is h = 2·cos((π/30)·t)
Step-by-step explanation:
The cosine function equation is given as follows h = d + a·cos(b(x - c))
Where:
= Amplitude
2·π/b = The period
c = The phase shift
d = The vertical shift
h = Height of the function
x = The time duration of motion of the wave, t
The given data are;
The amplitude
= 2 feet
Time for the wave to pass the dock
The number of times the wave passes a point in each cycle = 2 times
Therefore;
The time for each complete cycle = 2 × 30 seconds = 60 seconds
The time for each complete cycle = Period = 2·π/b = 60
b = π/30 =
Taking the phase shift as zero, (moving wave) and the vertical shift as zero (movement about the mean water line), we have
h = 0 + 2·cos(π/30(t - 0)) = 2·cos((π/30)·t)
The cosine function is h = 2·cos((π/30)·t).
Answer:

Step-by-step explanation:
we know that
The lateral area of the figure is given by

where
P is the perimeter of the base (larger faces)
h is the height
Find the perimeter of the base P

we have

substitute in the formula of lateral area
