(57 + 4) x 4 - 16 I need this for my math test

228

Step-by-step explanation:

(57 + 4) * 4 - 16

61 * 4 - 16( To get 61 solve the ones in brackets first)

244 - 16( Solve the multiplication to get 244 _ 61 * 4=244)

228 ( Then solve the subtraction - 244-16= 228)

SO THE ANSWER IS 228.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
