-2
<em>BRAINLIEST, PLEASE!</em>
Step-by-step explanation:
5 - 3(2a + 1) = -4a + 10
5 - 6a - 3 = -4a + 10
2 - 6a = -4a + 10
-2a = 8
a = -4
-4 + 2 = -2
Answer:
The triangle is a right triangle.
Step-by-step explanation:
Since The Pythagorean Theorem only works on right triangles, we can use this knowledge to prove whether this triangle is right:
![a^2 + b^2 = c^2\\10^2 + (2\sqrt{39})^2 = 16^2\\100 + (4 \times 39) = 256\\100 + 156 = 256\\256 = 256](https://tex.z-dn.net/?f=a%5E2%20%2B%20b%5E2%20%3D%20c%5E2%5C%5C10%5E2%20%2B%20%282%5Csqrt%7B39%7D%29%5E2%20%3D%2016%5E2%5C%5C100%20%2B%20%284%20%5Ctimes%2039%29%20%3D%20256%5C%5C100%20%2B%20156%20%3D%20256%5C%5C256%20%3D%20256)
Therefore, the triangle is right.
