Find the difference between 6/7 and 2/3 in lowest terms.
kramer

As per the problem,

we have been asked to find the difference of the given fractions.

The given fractions are \frac{6}{7} \ and \ \frac{2}{3}

\frac{6}{7}-\frac{2}{3}

Make denominator equal and simplify we get

\Rightarrow \frac{6}{7}-\frac{2}{3} =\frac{6}{7}*\frac{3}{3}-\frac{2}{3}*\frac{7}{7}  \\\\\Rightarrow \frac{6}{7}-\frac{2}{3} =\frac{18}{21}-\frac{14}{21} \\\\\Rightarrow \frac{6}{7}-\frac{2}{3} =\frac{18-14}{21}\\\\\Rightarrow \frac{6}{7}-\frac{2}{3} =\frac{4}{21}

The difference of the given fractions=4/21

Triangle xyz is similar to triangle xvw. write the congruence statements that must be true.
Lunna [17]

Answer:

∠ Y = ∠ V

∠ Z = ∠ W

\frac{XY}{XV} =\frac{YZ}{VW} =\frac{XZ}{XW}

Step-by-step explanation:

It is given that Δ XYZ is similar to Δ XVW.

Since corresponding angles of similar triangles are equal,

∠ X = ∠ X

∠ Y = ∠ V

∠ Z = ∠ W

Also, since corresponding sides of similar triangles are in proportionate,

\frac{XY}{XV} =\frac{YZ}{VW} =\frac{XZ}{XW}

Answer:

\huge\boxed{\sf All \ right \ angles \ are \ congruent}

Step-by-step explanation:

Since it is given that HK ⊥ IJ, This means that it is a right bisector (Dividing the straight line into two angles of 90 degrees)

So,

∠HKI ≅ ∠HKJ (Both of tem are right angles and are equal to 90 degrees)
