Answer:
140.4
Step-by-step explanation:
The sum of the angles in a triangle is 180°, then:
68°+26°+x°=180°
Solve it as an equation:
68+26+x=180
x=180-68-26
x=86°
First, move like terms on one side. Next, add them and divide. See the attachment for solution.
61,400 is the answer. Since 61 is closer to 100 than 0, you round up.
Answer:
y = 4sin( π/12) + 5
Step-by-step explanation:
For a sinusidal function :
y = Asin(w + c) + s
Where ; A = amplitude ; w= angular velocity, s = vertical Displacement, c = phase angle
A = (maximum - minimum) / 2
A = (9 - 1) /2 = 8/2 = 4 feets
w = 2π/T ; T = 24
w = 2π/24 = π/12
s = (maximum - minimum) / 2
s = (9 +1) /2 = 10/2 = 5
c = 0
Plugging our values into the general equation :
y = Asin(w + c) + s
y = 4sin( π/12) + 5
