Answer:
1. 45 minutes a day cycling
2.$1.55 on each cup of coffee a day
Step-by-step explanation:
1. You would figure up how much he jogs per week by multiplying 15 times 5 which would be 75 minutes and then from there you would subtract 75 from 300 and get 225 and divide 225 and 5 and end up with 45
2. You would multiply $.75 by 4 to figure up how much he spends on donuts which is $3 and then subtract 15.40 from 3 and get 12.40 and divide 12.40 by 8 since he goes twice a day and end up with 1.55
Answer:
Sin, Cos, Tan and others are used to calculate the ratios of the sides of a right angled triangle by taking a certain angle as the angle of reference.
On the other hand, Sin‐¹, Cos‐¹ and Tan-¹ are used to find the reference angle used to calculate the ratio of sides.
For this question,
we need to find which option should used to calculate the angle the slide makes with the vertical support.
So the option will have to be either A, C or E.
here, the base is 2.81m and hypotenuse is 3.64m.
we know, Cos = base / hypotenuse
So the angle is given by Cos-¹(2.81/3.64)
Option C
