Number 1 is B
Number 2 is also B
Angle O=64
Side m=7.3159882(rounded if needed)
Side n=16.68902(round if needed)
We are given
Angle M which equal 26.
Angle N equals 90 degrees
Side MN which equal 15.
We are asked to find all the missing elements of the triangle.
- Angle O can be found using triangle interior theorem so we can add 90+26+x =180 to find the value that satisfies the x value.



Angle O=64 degrees
We can find side m by doing law of sines.



which is 7.315(round if neeeded).
We can find side n using pythagorean theorem,



Side n=16.689(round if needed)
Express it as a decimal.
3/20 = 0.15 by division
then move the decimal point twice to the right and affix the percent symbol
thus, 15%.
Answer:
(1, -3/2)
Step-by-step explanation:
The x coordinate is the same for both endpoints so the x coordinate for the midpoint is 1
The y coordinate for the midpoint is found by adding the two y coordinates and dividing by 2
(2+-5)/2 = -3/2
The midpoint is
(1, -3/2)
