Step-by-step explanation:
Please see attached drawing of the proof created with Microsoft Word
The two column proof can be presented as follows;
Statement 
Reason
Given
m∠3 + m∠4 = 180° Linear pair postulate
∠1 ≅ ∠3 Corresponding Angle Theorem
m∠1 + m∠4 = 180° Transitive Property
m∠1 and m∠4 are supplementary Definition of supplementary angles
Answer:
I think it's D. The independent variable is the length of the race. The dependent variable is the time.
Step-by-step explanation:
Here I'm quoting user kaylaj051903 "because an independent variable is something that is constant and does not change throughout the problem. The dependent variable depends on the independent variable. The race is a 5K race. That will not change. What will change is how long it takes Stephanie to run the 5K race."
Answer:
67°
Step-by-step explanation:
A right angle = 90°
90° - 23° = x° = 67°
Answer:
the value of x in this image is 38
Step-by-step explanation:
we know that the total angles of triangles are 180, so m is 180-84=96, and 180-134=46, when added we get 142, which means the last angle is 38
