Answer:
125
Step-by-step explanation:
all angles in a triangle add up to 180. you add 100+25=125 180-125=55 to check... 125+55=180 to angles next to each other on a straight line equals 180-55=125 angle x= 125
im pretty sure thats correct i hope this helps!
z = -4050
x × y × z
90 × 45 × z
4050 = -z
4050 = -z \ × -1
-4050 = z
