The sum of opposite angles are equal, so two of the angles are 45°. The sum of all angles about the intersection of two lines is 360°. So the remaining two angles are found by:
α=(360-2*45)/2
α=135° thus all four angles are:
45°,135°,45°,135°
Answer: c is perpendicular to y = -5x - 2
Explanation: The slope of a perpendicular line is an opposite reciprocal of the original slope/line. (Basically switch the numerator and denominator and the sign. In this case, the slope is -5/1x. It’s opposite reciprocal is 1/5x.)
You can take a look at my notes for further clarification. Hope this helps!
Answer:
the answer is 14 2/3, hope this answers your question
Step-by-step explanation:
Answer:
Step-by-step explanation:
If that is a square, then all sides are the same. Therefore, it's a 
by shape. We'll use Pythagorean Theorem to find the diagonal.
Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!
