Answer:
x = -4
Step-by-step explanation:
logs (8 - 3x) = log20
Since we are taking the log on each side
log a = log b then a = b
8 -3x = 20
Subtract 8 from each side
8 -3x-8 =20 -8
-3x = 12
Divide by -3
-3x/-3 = 12/-3
x = -4
Answer:
Angle 5 = 35 degrees
Step-by-step explanation:
A straight line is equal to 180 degrees, meaning 1 + 2 + 5 = 180 degrees because they make up a straight line.
Angle 2 = 55 degrees
Angle 1 = 90 degrees (because it is a right angle)
Angle 5 = ?
Set up an equation:
90 + 55 + angle 5 = 180
145 + angle 5 = 180
Angle 5 = 35
