The ladder is 7 foot up the wall if the ladder if the ladder is 3 ft away from wall.
assuming the wall and ground make a 90 degree angle with one another, Pythagorean's Theorem states the ladder will go 8 feet up the wall.
Using Pythagoras' theorem the length of the base is 7 feet

Round the base angle to 70 degrees and use the sine ratio: 30*sine 70 degrees = 28.19077862 feet Height of ladder from the ground = 28 feet to 2 s.f.
1 metres

Use the cosine ratio: 5.437846722 meters

It should be placed 2 ft from the wall
Using Pythagoras' theorem the the foot of the ladder should be 12 feet away from the base of the building.
3 FEET

15 meters, or less, depending on the angle.
1/4 the height of the ladder. (flat top on rungs should be level when ladder is placed right.
