A 20 ft ladder is leaned aginst a verticals wall the distince from the foot of the ladder to the wall is 5 feet

b=5sqrt(15)

Explanation:

In this situation, this creates a right triangle

the 20 is c, the 5 is a

a^2+b^2=c^2, 25+b^2=20^2, b^2=375, b=5sqrt(15)

i am a little confused myself with what goes with the letters and what goes with the numbers but ill do my best to you

the cordillera states and grand canyon are along the southwest u.s. and northern mexican pacific.

the great plains and southwest desert are also the prairie and home to many earthquakes too .

the coastal plains have poor soil and many factories started in the south.

is this what u needed? if not i can see what i can do

the correct answer would be true friction causes the faults to slip or collide
