Hello!
Supplementary angles add up to 180. This gives us the system of equations below.
a+b=180
b= 4a+20
Now we plug our b value into the first equation and solve for a.
a+4a+20=180
We combine like terms.
5a+20=180
We subtract 20 from both sides.
5a=160
We divide both sides by 5.
a=32
Now we want to find our angle b. We can plug our a value into the equation.
b=4(32)+20
128+20=148
Therefore, our angle measure is 148°.
I hope this helps!
This is my thinking;
To convert meters to kilometers, in decimals, its 0.001. So converting that into kilometers, that would be 0.057

Recall that the change of base formula is 
Answer:
34 + x = 70 ; 36
Step-by-step explanation:
Given that:
Current amount = 34
Final amount = 70
Number of roses planted by the workers today ;
Current amount + number planted today = final amount
Let number planted today = x
34 + x = 70
x = 70 - 34
x = 36
