Answer:
equation of line: y = 2x + 5
Explanation:
using the formula:
The equations presented in the choices above are all derived from the Pythagorean theorem. This states that the sum of the squares of the two shorter sides is equal to the square of the longest side which is also referred to as the hypotenuse.
If the sum of the squares of the shorter sides is smaller compared to the square of the hypotenuse then, the triangle is OBTUSE. The answer therefore to this item is letter A.

- Simplify ⇨ 9 + 5 (4x - 4)


Use the distributive property to multiply 5 by 4x-4.

Subtract 20 from 9 to get -11.

Putting it in standard form...(positive number in the 1st)

X = 80 - 15
x = 65
answer
65 degrees
