Answer:

64°

Step-by-step explanation:

Using Pythagoras rule :

Cosθ = adjacent / hypotenus

Adjacent = 167

Hypotenus = 381

Cosθ = 167 / 381

Cosθ = 0.4383202

θ = Cos^-1(0.4383202)

= 64.003

Hence, angle of elevation = 64°

lutik1710 [3]

Answer:

54 minutes

Step-by-step explanation:

We can write a proportion to solve this problem.  Put the number of pages over the minutes

27 pages           324 pages

--------------    = ---------------

4.5 minutes         x minutes

Using cross products

27 * x = 324 * 4.5

27x = 1458

Divide each side by 27

27x/27 = 1458/27

x =54

2.5h= min pls answer me quick pls​
Effectus [21]

Answer:

2.5h = 150 min.

Step-by-step explanation:

An hour is 60 minutes.

A half an hour is 30 minutes.

Two hours = 1 hour + 1 hour = 60 minutes + 60 minutes = 120 minutes

2.5 hours = 2 hours + 1/2 hour = 120 minutes + 30 minutes = 150 minutes

2.5h = 150 min.

Hope this helps.
