Answer:

<h3>★ Value of x is <u>8.1</u>.</h3>

<h3>★ Value of H is <u>12.8676</u>.</h3>
Remember:
- tan∅=Perpendicular/Base
- sin∅=Perpendicular/Hypotenuse
So the math here is 1+1 = 2
Answer:

Step-by-step explanation:
Required
Which is ordered in ascending order
To do this, it is best to convert the fractions to decimal and then make comparison.
From the options, only (b) is ordered in ascending order and the proof is as follows.

Convert to decimals

By comparison:

Hence, (b) is ordered from least to greatest
We know, speed = distance / time
s = 1.5/7.5 = 0.2 Km/m
Now, distance = speed * time
Here, t = 1 min.
s = 0.2 Km/m
d = 1 * 0.2 = 0.2 Km
In short, Your Answer would be -2
Hope this helps!
