Answer:
I thinks it’s A but I’m not really sure
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
Since it is on a right angle we can equation the sum of both angles to 90:
6x-2+20 = 90
Now we simplify:
6x+18=90
Now we subtract 18 from both sides:
6x+18-18=90-18
Simplify:
6x=72
Now we divide both sides by 6:
6x÷6=72÷6
Simplify:
x = 12
12.5 by 5 and you will find your answer I believe
angle 1 + angle 3 = 27 +43 = 70
angle 2 = 180-70 = 110
angle 2 + angle 4 = 180
180 -angle 2 = angle 4 = 180-110 = 70
angle 4 = 70 degrees
