A cyclist is riding a bicycle whose wheels have a diameter of 76 centimeters . Suppose she is traveling at 33 kilometers per hour . ( A useful fact : 1 km = 1000 m . ) ( a ) Find the angular speed of the wheels in radians per minute . ( b ) Find the number of revolutions the wheels make per minute . Do not round any intermediate computations , and round your answer to the nearest whole number .

i believe the answer is the polygon, heptagon.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
