Answer:
360°
Step-by-step explanation:
We need only remember that the sum of the measures of the interior angles of a triangle is 180°. Angle c and 112° form a pair of "straight angles," so they add up to 180°; as a consequence, Angle c = 180° - 112°, or 68°.
With two of the interior angles now known, we can calculate the third, Angle A: It is 180° less (51° + 68°), or 180° - 119°, or 61°.
That means that the measure of Angle B is 180° - 61° = 119°
Looking at the pair C and 112°, we identify the exterior angle as 112°.
Looking at the pair A and B, or 61° and 119°, we identify the exterior angle as 119°.
Finally, looking at the pair 51° and (180° - 51°), or
51° and 129°, we identify the exterior angle as 129°.
Then the sum of the exterior angles 129° and 119° and 112° is 360°.

Answer:
3 3/16
Step-by-step explanation:
You want s such that ...
(2 1/2)/(3 1/3) = s/(4 1/4)
Multiplying by 4 1/4 gives ...
s = (4 1/4)(2 1/2)/(3 1/3)
A calculator can help you find the value of this expression. As a decimal, it is ...
3.1875
If you're familiar with decimal equivalents of fractions, you know this can be written as the mixed number ...
3 3/16
_____
If you do the above math the "pencil and paper" way, you get ...
s = (17/4)(5/2)/(10/3) = (17·5·3)/(4·2·10) = 51/16 = 3 3/16
Answer
i believe the answer would be the third photo if the third photo for you is the one that doesn’t pass the vertical line test
Explanation
if the relation is a function no two pints should touch going down hence the vertical line test
hope this helps and have a wonderful day :)
