Answer:
Angle B is 120°
Step-by-step explanation:
Since it's a supplementary angle (angles that add up to 180°) on top of the triangle, you would find ∠B by subtracting 180 by 60 and ∠B will be 120°. Hope this helps:)

A golf ball is hit with an initial velocity of 64 Ft/s. The function h(t) = -16t^2 + 64t models the height h (in feet) of the golf ball at time t (in seconds). Does the golf ball reach a height of 60 ft?
Answers
Answer:
Yes, the ball reaches the height of 64 ftStep-by-step explanation:
Given function
h(t) = -16t^2 + 64tThe maximum value is at vertex and the x-value of the vertex is:
t = -64/2(-16) = 2Finding the maximum height the ball can reach:
h(2) = -16(2²) + 64(2) = -64 + 128 = 64The answer is yes

measure 1 and measure 2 are supplementary. if measure 1 equals (3x - 17) degrees in measure angle two equals (5x + 21) degrees find the value of x
Answers
Answer:
x = 23 degrees
Step-by-step explanation:
Supplementary angles add up to 180 degrees. Thus, 3x - 17 degrees plus al 5x + 21 deg must equal 180 degrees.
Combining like terms, we get 8x - 4 = 180, or 8x = 184.
Dividing both sides by 8 yields x = 184/8 = 23 = x (measured in degrees)

Area of the rectangle is given by the polynomial function A(x)=2x^2+18x. If the width of the rectangle is 2x what is the length?
Answers
The length of the rectangle is x + 9 whose width is gives as 2x.
To find the length of the rectangle, we need to express it in terms of the width.
Given:
width of the rectangle is 2x.
The formula for the area of a rectangle is
A = length × width.
As, the polynomial function for the area:
[tex]A(x) = 2x^2 + 18x[/tex]
So, set up the equation:
[tex]2x^2 + 18x =[/tex] [tex]{\text} width x length[/tex]
Substituting the given width = 2x in above equation gives
[tex]2x^2 + 18x = 2x * length[/tex]
Dividing both sides of the equation by 2x:
x + 9 = length
Therefore, the length of the rectangle is x + 9.
