(6x-1)+20+(x+14)=180
6x-1+20+x+14=180
6x+x+20+14-1=180
7x+33=180
-33 -33
7x=147
7/7x=147/7
x=21
Measure of angle A=:
(6x-1)
6x-1
6(21)-1
126-1
125
Measure of angle A is 125°
Measure of angle C=
(x+14)
x+14
21+14
35
Measure of angle C is 35°
Answer:
Option D is correct.
Step-by-step explanation:
The relationship between any point on an ellipse and each of its foci is:
The sum of the distances to each focus equals a certain constant. The constant will be 2a
If d₁ and d₂ are the distances then their sum is d₁ + d₂ = 2a.
Option D is correct.

Vertical angles are congruent/equal :
Thanks for sitting tight. Answers in attachment below.
*Percentages are close approximations to the probabilities. Ideally, the fractions should be used.
Answer:
90 degrees
Step-by-step explanation:
supplementary angles equal 180 degrees
so that means complementary angles equal 90 degrees
