Answer:
53 degrees
Step-by-step explanation:
Complementary angles add to 90 degrees
a+b = 90
a=37
37+b = 90
Subtract 37 from each side
37+b-37 = 90-37
b =53
Solve the multiplication first then the division and the subtract them to get something like this:

which simplifies to 29.7 (3 significant figure )
Answer:

Step-by-step explanation:
The constant of proportionality is the slope of the line joining the two points
(70,40) and (49,28).
Recall the slope formula:

We substitute the point to get:

<u>Alternatively</u>:
A proportional relation is given by

where k is the constant of proportionality.
Using any point, we substitute and solve for k.


(x+3)^4=(x+3)^2)^2=(x^2+6x+9)^2=x^4+36x^2+81+12x^3+108x
I believe it would be all of the above let me know if it is right
