Answer:
x=40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+102+38 = 180
Combine like terms
x + 140 = 180
Subtract 140 from each side
x+140-140 = 180-140
x = 40
Either 1 or 3 - 1 is all positive and 3 is all negative
Divide 3400 by 0.85 to get 4000
Answer: 4000
Answer:
Step-by-step explanation:
To be perpendicular m1(m2)=-1
-1m/7=-1
m=7
So the perpendicular line will have 7 as the linear coefficient
y=7x+b
