We sketch two triangles, DFE and DGH, as shown below 

Side DF correspond to side DG, the scale factor is 40÷32=1.25

Side DE correspond to side DH, the scale factor is 30÷24=1.25

That leaves us with the last corresponding sides, EF and HG which would also have a scale factor 1.25

Both triangles share the same angle D

We can conclude triangle DFE and triangle DGH are similar for property SSS and SAS

John's commute to work is 20kmhr while Sheri's commute is 500mmin. Who has the fastest commute to work in mihrif 1.61km=1mi? A S
Andreyy89

Answer:

A) Sheri has the faster commute by 6.2 miles/hr.

Step-by-step explanation:

Given

John's commute to work =20\ km/hr

Sheri's commute to work  =500\ m/min

1.61\ km = 1\ mile

John's commute to work in miles per hour = \frac{20\ km}{1 hr}\times \frac{1\ mile}{1.61\ km}= 12.42\ miles/hr

Sheri's commute to work in miles per hour =\frac{500\ m}{1\ min}\times \frac{1\ km}{1000\ m}\times \frac{1\ mile}{1.61\ km}\times \frac{60\ min}{1\ hr}= 18.63\ miles/ hr

We can see that Sheri has a faster commute.

Difference between the rates =18.63\ miles/ hr-12.42\ miles/hr=6.21\ miles/hr\approx 6.2\ miles/hr

∴ Sheri has the faster commute by 6.2 miles/hr.

"Based on the figure, which pair of triangles is congruent by the Side Angle Side Postulate?
Irina18 [472]
<span>According to the figure, the two lenghts AE and EC are congruents, and so are AE and ED.Besides the two lines AB and DC are parallels, consequently angle A and C are congruent (interior Alternate angles). All this statements tell that triangle ABE and Triangle DEC congruent by the Side Angle Side Postulate, so the true answer is B.) Triangle AEB and Triangle CED</span>
