Tan(44) = X/140 (X is the height of the pole prior to adding the 4 foot stand)

X = Tan(44) (140)

X = about 135

Add the remaining 4 from the stand

About 139 feet. (<- Your Answer)

Which makes sense considering a 45-45 triangle has same side lengths, and 44 is very close to 45, therefore the pole length will be very similar to the distance the person walked.

║a+9║/7=5
you multiply 7 on both sides which cancel out 7.

and now it would be a+9=35 and a+9=-35 then solve it.
35-9 and 9-(-35)= 26 and -44
hope this helped!

1.05f + 1.07d = ?

To solve this problem, you need to replace the variable with the amount of each item.

1.05(3) + 1.07(4) = ?

Now we can solve by multiplying and adding:

3.15 + 4.28 = ?
