Answer:
5 runners will be needed
Step-by-step explation:
To solve this problem you have to find how many 1/25ths it takes to get 1/5. You can do that by dividing 25 by 5 which eauals 5. In other words 5/25 is equal to 1/5. This means you will need 5 runners to complete the race.
Answer:
Angle B is 45°
Step-by-step explanation:
Since a and b are both of length 20, this is an isosceles right triangle, and the angle opposite side b must be 45°.
Answer:
6:10pm
Step-by-step explanation:
At 6:00 the hands are 180° apart.
The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.
The minute hand moves 1/60 of the circle per minute = 6° per minute
Angle between the hands decreases by 6-0.5 = 5.5° per minute.
180 - 5.5t = 125
t = 125/5.5 = 10 minutes
The hands are 125° apart at t minutes after 6:00, or 6:10.
The tangent of an angle is the trigonometric ratio between the adjacent side and the opposite side of a right triangle containing that angle. Example: In the triangle shown, tan(A)=68 or 34 and tan(B)=86 or 43 .
