Answer:
<em>Both equal sides have a length of 29 cm.</em>
<em>The third inequal side is 9 cm.</em>
Step-by-step explanation:
<u>System of Equations</u>
With the data provided in the problem, we can form a system of two equations with two unknowns.
Let's call x to each equal side of the isosceles triangle and y to the other side. One condition states that each equal side is 2 cm more than three times the other side. It can be written as:

We also know the perimeter of the triangle is 67 cm. Since we have to equal sides to x:


Let's put together both equations:


To solve the system, we can use the x from the first equation and replace it into the second equation:

Operating:

Joining like terms:

Solving for y:

The third inequal side is 9 cm. Now find the value of x.

Both equal sides have a length of 29 cm.
Answer:
Area = 1,527 in
Step-by-step explanation:
Circle area = π * r² = π * 3136 [cm²] ≈ 1527 [in²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 56 [cm] * 2 = 44.094 [inch]
Coterminal angles are angles that end in the same position on a unit circle.
We can find angles that are coterminal to -4pi/3 by adding and subtracting 2pi.
-4pi/3 + 2pi = 2pi/3
The answer is 2pi/3
Answer:
2233000x
Step-by-step explanation:
Let's say side length is s.
s*s = 500, so s = √500.
4 sides needed, total length thus 4*s.
4√500 ≈ 89.4
