HELP WILL MARK BRAINLIEST PLEASE ANSWER ALL THREE

Step-by-step explanation:

8. ∠COB and ∠AOD are vertical angles or C

9. Vertical angles are equivalent to each other so 4x-16 = 112°

4x - 16 = 112°

4x - 16 + 16 = 112 + 16

4x = 128

4x/4 = 128/4

x= 32° or D

10. ∠AOC is vertical to ∠DOB therefore the 2 angles are congruent

You can do 360 - (112 + 112) = 2AOC

360 - 224 = 2AOC

136 = 2AOC

AOC = 68°or A

OR

You could just do 180 -112

Since ∠AOD and ∠AOC are supplementary angles, they both add up to 180°

We already know the measure of ∠AOD, it's 112°

So all you would need to do is subtract 112 from 180

And you get 68° or A

I REALLY hope this helps!!!

the answer is 375 miles

step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
