I have attached an image of the right trapezoid.
Answer:
C: 107°
Step-by-step explanation:
From the image attached, we can see that the right trapezoid has 2 internal angles which are right angles while it has a third angle which is 73°.
Now,we want to find angle WXY.
Sum of angles in a trapezoid is 360°.
Thus;
90 + 90 + 73 + ∠WXY = 360
253 + ∠WXY = 360
∠WXY = 360 - 253
∠WXY = 107°
Answer:
12.8x + 20
Step-by-step explanation:
I have the same question and i figured it out so here you go!!!
A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
ω = 5 revolutions per minute. 1 minute = (1/60) hour.
= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14
= 600*3.14 = 1884 radians / hour
but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile
Linear velocity, v = ωr
v = 1884 radians / hour * (10/5280) mile
v ≈ 3.568 miles / hour
