Answer:
y = x + 1
Step-by-step explanation:
x - y = -1
-y = -x - 1
y = (-x - 1) ÷ -1
y = x + 1
Answer:
Step-by-step explanation:
The pool are is divided into 4 separated shapes: 2 circular sections and 2 isosceles triangles. Basically, to calculate the whole area, we need to find the area of each section. Due to its symmetry, both triangles are equal, and both circular sections are also the same, so it would be enough to calculate 1 circular section and 1 triangle, then multiply it by 2.
<h3>Area of each triangle:</h3>From the figure, we know that <em>b = 20ft </em>and <em>h = 25ft. </em>So, the area would be:
From the figure, we know that and the radius is
. So, the are would be calculated with this formula:
Replacing all values:
Remember that
Therefore,
Now, the total are of the figure is:
Therefore the area of the symmetrical pool is
Answer:
64 degrees
Step-by-step explanation:
Since the triangles are similar they have the same angle measures
∠P = ∠S ∠R =∠U ∠Q=∠T
We know 2 of the angle measures: ∠S and ∠R, and since they are similar we know ∠P and ∠U
In triangles the sum of all angle measures is always 180 degrees, so we can solve for ∠Q with this formula
subtract 116 from both sides
Therefore ∠Q is equal to 64 degrees
