Answer:
The angle of elevation is equal to 68.2 degrees
Step-by-step explanation:
As you can see from the image below we are trying to find the angle on the bottom right.
We know that the hypotenuse is equal to 14 and we know that the opposite is equal to 14. This means that we will be using Sine.
sin x = 13/14
divide:
sin x = 0.9285714286
now we need to use sin^-1
sin^-1 (0.9285714286) = 68.21321071
Round 68.21321071 to the nearest tenth:
68.2
The angle of elevation is 68.2 degrees!
4 times as much as 3 is 12.
<h3>Further explanation </h3>Consider the following sentence:
X times as many as Y refer to X multiplied by Y
Therefore, the phrase 4 times as much as 3 is ... can be rewritten to 4 multiplied by 3 is ... .
We can say this is a simple multiplication operation, which is one of four basic operations, i.e.,
- addition,
- subtraction,
- multiplication, and
- division.
However, the case we face is only a multiplication, not accompanied by another operation.
Let's go back to our problem. We think naturally about this multiplication. 4 times 3 means there are two options like the following:
- Addition of 4 as many as 3 times (there are 3 terms).
- Addition of 3 as many as 4 times (there are 4 terms).
Actually both are the same, i.e., 3+ 3 + 3 + 3 = 12 or 4 + 4 + 4 = 12.
We state it quickly.
4 times as much as 3 is 4 x 3 = 12 or twelve.
