Answer:
(first and brainliest??) 27 degrees
Step-by-step explanation:
The top triangle's missing angle is 75 degrees because 85+20=105 and 180-105=75. Knowing this, we know that the angle that's connecting the two triangles is also 75 degrees. 78+75=153 and 180-153=27
X+y=6
x=10
10+y=6
y=-4
10=-4+z
-4+z=10
z=10+4
z=14
So the correct answer is 14
X= 7/93 or roughly 0.07526...
