Suppose bug B lands on the end of the wiper blade closest to the pivot. Assume the wiper turns through an angle of 120°. In one
adelina 88 [10]

Answer:

s = 8*π in

Step-by-step explanation:

Given:

- The complete data is given in the figure (attached):

Solution:

- The bugs lands on the end of the wiper blade closest to the pivot. The arc length (s) swept by a wiper in one cycle i.e θ = 120° would be given by:

                                     s = 2*r*θ

- Where, r: The distance between the bug and the pivot = 6 in

              θ : Angle swept in radians

- The distance travelled by the bug is s:

                                    s = 2*(6)*( 120 / 180 ) * π

                                    s = 8*π in

If O is the center of the circle and ABC = 24 degrees, what is the measure of BDC?
Brilliant_brown [7]

Answer:

  ∠BDC = 66°

Step-by-step explanation:

∠OCB ≅ ∠OBC, so is 24°. ΔDBC is inscribed in a semicircle, so ∠DBC is a right angle. That makes ∠BDC complementary to ∠BCD:

  ∠BDC = 90° -24°

  ∠BDC = 66°

The sides of triangle ABC are 4.5feet 7.5 ft and 9 ft.The area is about 17 square feet. Explain how to use the are of triangle A
Nuetrik [128]
In order to get the area of a triangle using sides, the formula that we are going to use is Heron's formula. This is after from "Hero of Alexandria".
So here is the step by step process:
First, we calculate for s (half of the triangles perimeter) s = a+b+c divided by 2.
s = 6 + 10 + 12 / 2
s =28/2
s = 14
Now that we have the s, we can now calculate for the area.
A = square root of s(s-a)(s-b)(s-c)
A= square root of 14 x 8 x 4 x 2
A= square root of 896
A = 29.93
The area of triangle DEF is 29.93 square feet or 30 square feet. Hope this answer helps.
