Does anyone know these two they both have the same answer choices please help

7. yes, obtuse

8. no triangle

Step-by-step explanation:

7.

3, 7, 9

Do these side lengths form a triangle?

Add the two smaller numbers: 3 + 7 = 10

Since 10 is greater than 9, these three side lengths do form a triangle.

Now we qualify the triangle.

c^2 ? a^2 + b^2

The ? is there because we don';t know yet if it will be =, >, or <.

9^2 ? 3^2 + 7^2

81 ? 9 + 49

81 ? 58

Since 81 is greater than 58, now we know to use >.

81 > 58

Since c^2 is greater than a^ + b^2, the triangle is obtuse.

Yes these side lengths form a triangle, and the triangle is obtuse.

8.

4, 11, 16

Add the two small lengths: 4 + 11 = 15

Since 15 < 16, these three side lengths do not form a triangle.

no triangle

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.

step-by-step explanation:

told you

a)(x-2)^2+(y-1)^2=9
