Solve by Pythagorean theorem
c² = a² + b²
c² = 8² + 6²
c² = 64 + 36
c² = 100
c = √100
c = 10 blocks
13² = 5² + b²
169 - 25 = b²
b = √144
b = 12 feet
c > b
13 feet > 12 feet
Yes. The ladder will reach the top of the wall

Problem 1:
Solve by Pythagorean theorem
c² = a² + b²
c² = 8² + 6²
c² = 64 + 36
c² = 100
c = √100
c = 10 blocks
Problem 2:
Solve by Pythagorean theorem
c² = a² + b²
13² = 5² + b²
169 - 25 = b²
b = √144
b = 12 feet
c > b
13 feet > 12 feet
