If c^2 > a^2 + b^2 then the triangle is obtuse.
If c^2 < a^2 + b^2 then the triangle is acute.
If c^2 = a^2 + b^2 then the triangle is a right triangle.
13. 7^2 __ 3^2 + 6^2
49 ___ 9 + 36
49 > 47 obtuse
14. 12^2 __ 4^2 + 11^2
144 ___ 16 + 121
144 > 137 obtuse
15. 26^2 ___ 24^2 + 10^2
676 ___ 576 + 100
676 = 676 right triangle
16. 15^2 ___ 12^2 + 9^2
225 ___ 144 + 81
225 = 225 right triangle
17. 31^2 __ 30^2 + 10^2
961 ___ 900 + 100
961 < 1000 acute triangle

Please solve this question for a
ohaa [14]

Answer:

<h2>a =  \frac{8A}{\pi {r}^{2} }  + 1 \\</h2>

Step-by-step explanation:

A =  \frac{1}{8} \pi {r}^{2} (a - 1) \\

First of all multiply through by 8 to eliminate the fraction

That's

8A = 8 \times  \frac{1}{8} \pi {r}^{2} (a - 1) \\8 A = \pi {r}^{2} (a - 1)

<u>Divide both sides by πr²</u>

\frac{8A}{\pi {r}^{2} }  =  \frac{\pi {r}^{2}(a - 1) }{\pi {r}^{2} }  \\ a - 1 =  \frac{8A}{\pi {r}^{2} }

Move 1 to the other side of the equation to make a stand alone

We have the final answer as

a =  \frac{8A}{\pi {r}^{2} }  + 1 \\

Hope this helps you
