Answer:
The x coordinate is 7
The y coordinate is 2.5
Step-by-step explanation:
To find the midpoint, add the x coordinates together and divide by 2
(19+-5)/2 = 14/2 =7
Then add the y coordinates together and divide by 2
(2+3)/2 = 5/2 = 2.5
(7, 2.5)
The sum of two interior angles in a triangle is equal to an exterior angle that's supplementary to the third interior angle
2x - 2 = 45 + x
2x - x = 45 + 2
x = 47°
This would be labed as a Conditional probability
