Maurinko [17]

The Potential Energy, is given by:

PE=m\times g\times h

where:

m = mass of the object (in Kg)

g = gravity

h = height (in m)

Hence:

PE=20\times9.8\times100=19,600

Please help me with my math
boyakko [2]

Answer:

x = 115

z = 27

Step-by-step explanation:

x + 65 = 180 (same side interior angles)

x = 115

x = 3z +34 (alternate interior angles)

115 = 3z + 34

3z = 81

z = 27
