Tanα=h/x
x=h/tanα
x=70/tan38 ft
x≈89.6 ft (to nearest tenth of a foot)
Note: the question seems strange, (because this would make the ladder almost 114 feet long!) or are we to assume as I did that the ladder is leaning against a point 70 feet high, or should if be a 70 foot ladder leaning against a wall of unknown height?
If it is just a 70 ft ladder at a 38° inclination the:
cosα=x/L
x=Lcosα
x=70cos38° ft
x≈55.2 ft
We want to find total to red
total just add
14+8+12=14+20=34
red=8
total to red=34:8 or 34/8=17/4=17:4
I got +/- 7 for this one.............

We divide first number from first parenthesis with first number from second parenthesis. Then the resulting number we multiply by all numbers in second parenthesis and substract from first parenthesis.

We repeat previous steps until we run out of numbers:


We are left with a number that has no x inside. This is remainder.
The final solution is sum of all these solutions and remainder:
