Answer:
height of the leaning tower of pisa is 179 feet
it makes a 5.1 degrees from the vertical.
it's angle to the ground would be 90 - 5.1 = 84.9 degrees.
the height of the vertical would be one leg of a right triangle.
to find the vertical height of the tower, we would take the sine of 84.9 using the formula:
sine (84.9) = opposite divided by hypotenuse.
opposite i x
hypotenuse is 179
formula becomes:
sine (84.9) = x/179
multiply both sides of this equation by 179 to get:
x = 179 * sine (84.9)
this results in:
x = 178.2913507 feet
Step-by-step explanation:
When angles are restricted to real numbers, Bernhard is correct. The sine function has a range of -1 to 1 (inclusive).
_____
When angles are allowed to be complex numbers, the magnitude of the sine of an angle may exceed 1. In this realm, both Henrik and Bernhard are incorrect.
Answer:
The result is 60
Step-by-step explanation:
We have to use this expression showing BODMAS rule. According to the rule, we must first solve the brackets. In our expression, the term within the bracket is (12-4) squared = (8) squared = 64.
Then we need to perform the addition followed by subtraction.
The expression becomes:
11 squared - 64 + 3
= 121 - 64 + 3
= 124 - 64
= 60
So, the result of the expression is 60.
Let's find out together.
There are sixteen ounces in a pound, so 25 pounds (lbs) is 400 ounces (oz). 400>384.
So, 25 lbs is bigger than 384 oz.
