The front of an A-frame cottage has the shape of an isosceles triangle. It stands 23 feet high and is 15 feet wide at its base.
What is the angle of elevation of its roof
1 answer:
Answer:
The angle of elevation is 71.94 degrees.
Step-by-step explanation:
We are given the following in the question:
The front of an A-frame cottage has the shape of an isosceles triangle.
Height,h = 23 feet
Base,b = 15 feet
We have to find the angle of elevation of its roof.
The attached image shows the structure.
We use the relation,
Thus, the angle of elevation is 71.94 degrees.

Answer:
The smallest power of 10 that will exceed is
.
Step-by-step explanation:
We can use the following approach to determine the smallest power of 10 that will exceed M. We can transform that number into scientific notation, which is of the form:
,
Where:
- Integer part, formed by a digit, which is of the highest order.
- Decimal part, formed by a digit onwards.
- Power grade.
The smallest power of 10 that will exceed M is
If , then, the power grade is number of spaces that dot must be moved leftwards. In this case, dot must be moved 5 spaces on the left. The integer part is 1 and the decimal part is 1852665902. Then, the value of
in scientific notation is:
Then, the smallest power of 10 that will exceed is
.
