Answer: The sum of the measures of the angle inside of a triangle add up to 180 degrees. That's all we're doing over here. And so let's see if we can simplify this a little bit. So these two guys-- 90 plus 90's going to be 180, so you get 180 minus theta …

Answer:
Yes! Our total savings on gas proportional to the number of beverages you purchase.
Step-by-step explanation:
Here, each liter of gas costs $3.
Every beverage you purchase you save $0.20.
So, if you purchase for $9, you will save 3*$0.20 = $0.60
So, this is proportional because when increase in purchase, there is proportional increase in savings.
The two numbers are (9+ 5√5)/2 and (9- 5√5)/2.
(9+ 5√5)/2+ (9- 5√5)/2= 9
(9+ 5√5)/2* (9- 5√5)/2= -11

Answer:
D. 10
Step-by-step explanation:
Assuming that <COA is a right angle, we can say that the two given angles are complementary
complementary angles are angles that add up to 90 degrees
this means we can create this equation: 3x + 46 + 14 = 90
so subtract 46 and 14 from 90: 3x = 30
divide both sides by 3: x = 10
