Answer:
a.Angle. 3
Step-by-step explanation:
Angle 3 is complementary to angle 4.
Because 70+20=90°
I’m pretty sure the slope is -1/2
Answer: 69
Step-by-step explanation: a triangle adds up to 180 degrees. It is an isosceles triangle (2 sides are the same angle) 180-42=138 then do 138/2=69
Let y = f(x)
y = ln(3x)
Exchange place with x and y.
x = ln(3y)
Solve for y.
y = (e^x)/3
Replace y with the inverse notation.
f^(-1) x = (e^x)/3
Done.
It could be the first one or the third the others are not actual measuring units
im going with the first one
