Answer:
1.3
Friend is wrong
Step-by-step explanation:
Given:
friend's claim: height of his building is more than 1.50 times the height of yours
line of sight to the top edge of the other building makes an angle of 21° above the horizontal
line of sight to the base of the other building makes an angle of 52° below the horizontal
Solution:
Let A be the height of your building is A
Let B+A his building is B higher than yours.
Let the distance between the buildings is x.
then
tan 52 = A/x
tan 21 = B/x
A/B = tan 52 / tan 21
= 1.27994 / 0.38386
A/B = 3.33
(A + B) / A = 1.5
0
A/A + B/A = 1.50
1 + B/A = 1.50
B/A is basically (B/x) / (A/x)
So
1+ 3.33 / 3.33
= 4.33/3.33
= 1.3
Since 1.3 is not equal to 1.5
Hence the friend's claim is wrong.
0.504854369 as a percentage would be 50.4854369%
easiest way to remember: a percentage is a decimal rounded 2 decimal places to the right
rounded to the nearest tenth, the percentage will be 50.5%
if u need more help tell me
Answer:
Yes
Step-by-step explanation:
A square is a quadlirateral.
A rectangle is a quadrilateral.
These symbols are called operators.
Mathematics is the science that relates everyday practices and nature to human reasoning and numerical logic.
<h3>Math Operations</h3>
The four basic math operations are present in your day-to-day life, for example: when you pay your bills. The math operations are:
- addition - represented by symbol "+"
- subtraction - represented by symbol "-"
- multiplication - represented by symbol "x"
- division - represented by symbol "÷"
These symbols, also, are known as arithmetic operators.
Note that in math expressions, it is necessary to apply the rule of operations: parentheses, exponents, multiplication/division, and addition/subtraction.
