All triangles must equal 180°. So there you have a right angle which = 90° and a 25° angle. add those together to get 115°. Now do 180-115=65°. the missing angle is 65°.

So we all know that a triangle has 180°, and we know that we have a 25° and a 90°, so you just need to add those two numbers together which is equal to 115, and then 180 minus 115, which is 65, so the final answer would be 65°. Hope this helps!!!!

Enter the degree of the polynomial below.<br> 6x^6+ 9x^3+ 3x^2 - 4x^10 - 9x^5 – 5x^6
mafiozo [28]

The degree of a polynomial is simply the monomial with a coeficient that has the highest degree.

6x^6 = 6 degree

9x^3 = 3 degree

3x^2 = 2 degree

-4x^10 = 10 degree

-9x^5 = 5 degree

-5x^6 = 6 degree

Because -4x^10 has the highest degree, the degree of this polynomial is 10.
