It is an application of Pythagorean Theorem
And it is clear that the lower angle is 30 and the apex angle is 60 (this is how always normal TVs look like) ... refer to the image I attached
So, to calculate the width and the length:


You can after that round the length to be 22.517 in
Hope you got the idea
First, subtract 2/3 from both sides and you get

Then multiply both sides by 6/5 and you get
Apply the Pythagorean Theorem here.
Square the lengths of the 2 shorter sides: (20 mi)^2 and (40 mi)^2. Correct results are 400 and 1600. Combine these: obtain 2000.
Then the length of the diagonal (which is the distance between the 2 cities) is
sqrt(2000) = sqrt(400)*sqrt(5) = 20 sqrt(5) (answer)
Answer:
0.5 inches per month
Step-by-step explanation:
There are nearly 0.3937 inches in 1 cm, so

There are 12 months in the year, so'
15 centimeters per year is equivalent to

ANSWER:
[vii] By tangent property,
- 2y + 11 = 7y – 9
- 2y – 7y = – 9 – 11
- – 5y = – 20
- y = 4
Now, 8x – 35 = 5x – 8
- 8x – 5x = – 8 + 35
- 3x = 27
- x = 9
And LO = LM
LO = 32 – (2 × 4 + 11)
LO = 32 – (8 + 11)
LO = 32 – 19
LO = LM = 13
So, Perimeter = 13 + 32 + 37 + 37 + 19
