Answer:
8:10am
Step-by-step explanation:
You have to leave home because it takes you 15 minutes to walk to the bus stop so that will be 8:25am
takes you half an hour to get to job 8:55am
then 5 minutes to check in and you will be on time
Answer 8:10am
See also Tangent to a circle). In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). ... In a formula, it is written simply as 'tan'.
Answer:
D
Step-by-step explanation:
You can use the sin function to solve this.
Think of a triangle with the conveyor being the longest side (hypotenuse). The height (the vertical side) is H=17m. The angle of elevation is a=36.2. We are looking for length of the hypotenuse, L.
The sin is the ratio of height to hypotenuse: sin(36.2) = H/L = 17/L
Now solve for L:
L = 17/sin(36.2) = 17m/0.59 = 28.78m
The conveyor needs to be approx. 28.8m long to get close to the max. efficient angle.
