Answer:
Hello! answer: 49
Step-by-step explanation:
This is a complementary angle meaning it will add up to 90 degrees so...
90 - 41 = 49 therefore a = 49 hope that helps!
Answer:
17
Step-by-step explanation:
| 9- (- 8) | = | 17 | = 17
Basically the absolute value of N1 - N2
Answer:
56√93 ≈ 540 ft²
Step-by-step explanation:
The roof is made up of 4 congruent isosceles triangles. Since the roof extends 2 ft over the edge of the cottage on each side, then the base of each triangle is 26 + 2 = 28 ft.
Let's calculate the area of one of the triangles and then just multiply by 4. See attachment. Drop a perpendicular from the vertex of a triangle to its base. We now have the triangle broken up into two right triangles. The hypotenuse is 17 ft and one of the legs of the right triangle is 28 / 2 = 14 ft. Then the height / other leg is:

We now have the dimensions of each triangle: the height is √93 and the base is 28. The area of a triangle is: A = (1/2) * b * h, so we have the following.
A = (1/2) * b * h
A = (1/2) * 28 * √93 = 14√93
Multiply this by 4:
14√93 * 4 = 56√93
The total surface area is 56√93 ≈ 540 ft².
So if ever looking for % of, and you have a calculator a very simple way of doing it is taking your actual amount ($74.00) and multiplying it by 0.26
0.26, mathematically is like saying 26% of
The answer is 19.24
You'll notice if you type 74 x 0.50 (which is 50%) you will get 37 -- exactly half of 74
