Triangle MNO is similar to triangle RPO. Triangle M N O. Side M N is 20 kilometers and side M O is 32 kilometers. Triangle R P O. Side O R is 48 kilometers. Valek finds the distance between P and R. His work is shown below. Step 1 StartFraction 32 Over 48 EndFraction = StartFraction 20 Over P R EndFraction Step 2 20 P R = (32) (48) Step 3 20 P R = 1,536 Step 4 P R = 76.8 kilometers What is Valek’s first error? Valek did not correctly divide 1,536 by 20 going from step 3 to step 4. Valek did not find the correct product of 32 and 48 going from step 2 to step 3. Valek should have written the proportion in step 1 as StartFraction 32 Over 20 EndFraction = StartFraction P R Over 48 EndFraction. Valek should have written the cross-product in step 2 as 32 P R = (20) (48).
