Find the value of x in each triangle (pls i need this is a test grade)

x=125°

Step-by-step explanation:

100° + 25° =125°

180°- 125° = 55°

and since adjacent angles on a line equal 180°

180° - 55° = 125°

x= 125°

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
