Answer:
/A = 30°
/B = 150°
Step-by-step explanation:
Given that the lines are parellel.
Then /A+/B = 180° ( Consecutive interior angles)
Putting given values of angles
6x-18+ 14x+38 = 180
20x + 20 =180
20x = 160
x = 8
/A = 6x-18 = 6×8-18 = 30°
/B = 14x+38 = 14 × 8 +38 = 150°
Answer:
19)tu=12
20) true
Step-by-step explanation:
19) (22+5x)+(19-2x)=35
3x+41=35
3x=-6
x=-2
TU=22+5*-2
=12
Answer:
x>-2
Step-by-step explanation:
-35a^5b^5c^5 is the answer
Answer:
10:20
Step-by-step explanation:
