Answer:
AB = 8.857 cm
Step-by-step explanation:
Here, we are given a <em>right angle</em>
in which we have the following things:

Side <em>BC </em>is the hypotenuse here.
We have to find the side <em>AB</em>.
Trigonometric functions can be helpful to find the value of Side AB here.
Calculating
:
Sum of all the angles in
is
.

We know that <em>cosine </em>of an angle is:

So, side AB = 8.857 cm
.
Answer:
The width of lot B is 11 feet, so option A is correct.
Step-by-step explanation:
Given:
- Two rectangular properties share a common side.
- Lot A is 33 feet wide and 42 feet long.
- The combined area of the lots = 1,848 square feet.
To find:
How many feet wide is Lot B?
Solution:
we know that, area of a rectangle is length x breadth
Then area of lot A = 33 x 42 = 1386 square feet.
And area of lot B = width x 42
Now, we are given that, total area = 1848
area of lot A + area of lot B = 1848
1386 + width x 42 = 1848
width x 42 = 1848 – 1386
width x 42 = 462

width = 11
Hence, the width of lot B is 11 feet, so option A is correct.
Answer:
2.41
Step-by-step explanation:
Magnifcation = Image distance/object distance
Given;
Image distance = -53cm
Object distance = 22cm
Substitute
Magnification = 53/22
Magnification = 2.41
Note that the negative sign is not used in calculating magnification
