Answer:
x=7/2
DECIMAL= 3.5
Step-by-step explanation:
Add 55 to both sides
-2x=-4x+2+5−2x=−4x+2+5
2 Simplify -4x+2+5−4x+2+5 to -4x+7−4x+7
-2x=-4x+7−2x=−4x+7
3 Add 4x4x to both sides
-2x+4x=7−2x+4x=7
4 Simplify -2x+4x−2x+4x to 2x2x
2x=72x=7
5 Divide both sides by 22
x=\frac{7}{2}x= 2/7
Done
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
