Let p ↔ q represent the statement "He is wearing a coat if and only if the temperature is below 30°F.” Which represents p ∧ q? He is wearing a coat or the temperature is below 30°F. He is wearing a coat and the temperature is below 30°F. If he is wearing a coat, then the temperature is below 30°F. If he is not wearing a coat, then the temperature is not below 30°F.

the answer will be

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.
