Your teacher is giving a test that has 5 more four-point questions than six- point questions. The test is worth 120 points. Which system represents this information? (A) x +5=y; 4x + 6y=120 (B) x+y=5; 6x + 4y = 120 x-y=5; 6x + 4y= 120 (D) x-y=5; 4.x + 6y= 120​

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
