Problem 11
Answer: Angle C and angle F
Explanation: Angle C and the 80 degree angle are vertical angles. Vertical angles are always congruent. Angle F is equal to angle C because they are alternate interior angles.
============================================
Problem 12
Answer: 100 degrees
Explanation: Solve the equation E+F = 180, where F = 80 found earlier above. You should get E = 100.

Problem 13
Answer: 80 degrees
Explanation: This was mentioned earlier in problem 11.

Problem 14
Answers: complement = 50, supplement = 140
Explanation: Complementary angles always add to 90. Supplementary angles always add to 180. An example of supplementary angles are angles E and F forming a straight line angle.
By taking x as subject the formula becomes x = (v² - u²)/2a.
<h3>What is Equation?</h3>
An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.
Here given equation:
v² = u² + 2ax
2ax = v² - u²
x = (v² - u²)/2a
Thus, by taking x as subject the formula becomes x = (v² - u²)/2a.
