In the triangle below AC =_ cm.

AC = 5 cm

Step-by-step explanation:

STEP 1: Find the last side of the triangle using the Pythagorean theorem.

STEP 2: Solve the equation for  c.

STEP 3: Substitute the actual values into the equation.

STEP 4: Raise  3 to the power of  2.

STEP 5: Raise  4 to the power of  2.

STEP 6: Add  9 and  16.

STEP 7: Solve for .

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
