Which of the following is the correct If-Then statement for: The measure of a right angle is \( 90 \) degrees. If an angle is \( 90 \) degrees then it was measured with a protractor If the measure of an angle is \( 90 \) degrees, then it is a right angle. If it is a right angle, then it was measured. All right angles measure \( 90 \) degrees. 

5. Em um polígono, a razão entre a soma das medidas dos ângulos internos e a soma das medidas dos ângulos externos é igual a \( \frac{7}{2} \). Quantos lados tem esse polígono?

Si \( P=(1,1) \) y \( Q=(2,2) \), la magnitud \( (|\overrightarrow{P Q}|) \) y dirección \( (\theta) \) del vector \( \overrightarrow{P Q} \) son, respectivamente

Si \( P=(1,-1) \) y \( Q=(\sqrt{2},-1) \), la magnitud del vector \( \overrightarrow{P Q} \) es

\( (-9,-1) \) and \( (12,14) \) Slope \( = \)
