Well, from those 560, 200 are from her salary, and the rest is commissions from sales, so.... 360 is the 5.5% she's got, now, if we take "x" to be the 100% for the sales, then
solve for "x".
A. The figure is a triangular pyramid. You can findits surface area by adding up the area of the three faces of the triangle and the area of the base. A derived formula also is used where the SA is equal to 12 times the perimeter of base times the slant height, added to that is the area of the base. The area of the square base is s^2. Its perimeter is 4s.
SA of Pyramid = 12*P*l + s^2
SA of Pyramid = 12*4s*l + 16^2
SA of Pyramid = 12*4(16)*(17) + (16)^2
SA of Pyramid = 11,008 square inches
b.) The formula for the SA of a cone is:
SA of cone = πr[r+√(h^2+r^2)]
SA of cone = π(3)[(3+√(8^2+3^2)]
SA of cone = 108.8 square inches

Answer:
So here is how we are going to get the measure of angle 2.
Since given that angle COE measures 55°, we will equate m∠2 = 2x and m∠3 = x+10 with 55. So, 55 = 2x + x + 10
55 = 3x + 10
55-10 = 3x
45 = 3x << divide both sides by 3 and the result is
15 = x
So now that we know x, we can now solve for angle 2.
m∠2 = 2x
m∠2 = 2(15)
m∠2 = 30°
I hope that this is the answer that you are looking for.
Answer:
8.66 ft
Step-by-step explanation:
A square is a shape that has an equivalent length and breadth across it’s cross section.
What this means is that measuring the length across the top and bottom will yield the same length value.
Thus, mathematically, let’s call the measured height h
The square of this height gives the area
thus;
h^2 = 75
h = √75
h = 8.660254037844
This is approximately 8.7 to one decimal place
