Step-by-step explanation:
ok so there's a strategy I got taught ready?
100%- 96.
38%-x
~cross multiply~
100x= 3724
÷100 ÷100
________________
x=37.24
Hope this helps :D p.s- i recommend using this strategy :D
Divide across and just bring down the numbers

To find the length of the ladder, you need to do Pythagorean theorem.
50^2 + 30^2 = x^2
2500 + 900 = x^2
x^2 =3400
x= square root of 3400
58.31 OR 10 root34
To find the angle:
tan theta = opposite/adjacent
50/30 = 5/3
theta = tan inverse of 5/3
= 59.04
