Answer:
b=17.75 ft
Step-by-step explanation:
We will answer this using Pythagorean Theorem.
Since the bottom of a ladder is 3 feet from the wall, and the ladder is 18 ft long, the ladder is the hypotenuse. Knowing pythagorean theorem (a^2+b^2=c^2), we can plug it in.
3^2 + b^2 = 18^2
9+b^2=324
b^2=315
b=17.75 ft

Answer:
missing angle = 30 degrees
Step-by-step explanation:
all triangles have an interior angle or 180 degrees.
to find the missing angle, just take the know angles and add them together:
120 + 30 = 150
then take the sum and subtract it from 180:
180 - 150 = 30
3:8 is the original ratio
multiple both sides by 3 to make it 3 times greater
the answer would be 9:24
hope this helps!!
