is the angle of depression from the vertical cliff.
Option: A
Step-by-step explanation:
Given that, Height of the cliff (opposite side) = 40m
Distance of object from the base of the cliff (adjecent side) = 59.3m
To find the angle of depression of the object. From trigonometric rule in a right angled triangle, we know that 
Angle of depression = 
Therefore, the angle of depression to the object is .
To get to 20 minutes from 2 minutes you multiply by 10, do the same to the 30 problems to get 300. The answer is 300 problems in 20 minutes.
Answer:
Number of messages Salma sent = 7
Number of messages Brian sent = 16
Number of messages Chang sent = 32
Step-by-step explanation:
Let
Number of messages Salma sent = n
Number of messages Brian sent = n + 9
Number of messages Chang sent = 2(n + 9)
Total messages sent = 55
n + (n + 9) + 2(n + 9) = 55
n + n + 9 + 2n + 18 = 55
4n + 27 = 55
4n = 55 - 27
4n = 28
n = 28/4
n = 7
Number of messages Salma sent = n = 7 messages
Number of messages Brian sent = n + 9 = n + 9 = 16 messages
Number of messages Chang sent = 2(n + 9)
= 2(7 + 9)
= 2(16)
= 32 messages
Answer:
Height of the oblique prism is 18 units.
Step-by-step explanation:
Volume of an oblique prism = 
Area of the base of this prism = 24 square units
And volume of the prism = 144 cubic units
By substituting these values in the formula,
144 = 
h = 
h = 
h = 18 units
Therefore, height of the oblique prism is 18 units.
The answer here will be 1 2/3 because 5/3 is 1 2/3
