Answer:
The sum of the interior angles of a triangle is 180°. This fact is true for all triangles regardless of the type of triangle. An equiangular triangle has three equal angles which each measure 60°. ... The sum of the three angles of the triangle equals 180
Answer: 8 orchestra seats and 6 mezzanine seats.
Step-by-step explanation:
Let be "o" the number of orchestra seats they bought and "m" the number of mezzanine seats they bought.
Set up a system of equations:
You can apply the Substittution Method to solve the system of equations:
1. Solve for "o" from the second equation:
2. Substitute it into the first equation and solve for "m":
3. Substitute the value of "m" into and evaluate, in order to find the value of "o". This is:
Answer:
110 in²
Step-by-step explanation:
The area of a trapezoid is given by the formula ...
A = (1/2)(b1 +b2)h . . . . . . where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them.
In your problem, b1 and b2 are 13 in and 9 in, and h is 10 in. Putting these values into the formula, we find the area to be ...
A = (1/2)(13 in + 9 in)(10 in) = 110 in²
The area of the trapezoid is 110 square inches.
_____
First, we identify the appropriate formula to use for the geometry shown in the diagram.
Next, we determine from the diagram the values to use in the formula.
Last, we evaluate the formula and make a summary statement of results.

Step-by-step explanation:
Answer:
<h3><u><em>
sinA = 9/41</em></u></h3><h3><u><em>
ratio = 9:41</em></u></h3>
Step-by-step explanation:
<h2>
sin theta = opposite/ hypotenuse</h2>
ac = adjacent
ab = hypotenuse
cb = opposite
= cb/ab
= 9/41
<h2>
ratio = 9:41</h2>
