In order for two triangles to be similar, there must be 2 pairs of congruent angles. Since two angles of triangle PQR have different measures from two angles of triangle RST, it is impossible to have two pairs of congruent angles, so the triangles cannot be similar.

The answer is in bold type below.

AC=4, AE=7, AD=10, what is the length of AB? <br> A: 1 3/7 <br> B: 2 1/2<br> C: 5 5/7<br> D: 17 1/2
11Alexandr11 [23.1K]

Answer:

C. AB = 5\frac{5}{7}

Step-by-step explanation:

When two polygons are considered similar, the ratio of their corresponding sides would also be equal.

Since ∆ABC and ∆ADE are similar, \frac{AE}{AC} = \frac{AD}{AB}

\frac{7}{4} = \frac{10}{AB}

Cross multiply

7*AB = 10*4

7*AB = 40

Divide both sides by 7 to find AB

\frac{7*AB}{7} = \frac{40}{7}

AB = \frac{40}{7}

AB = 5\frac{5}{7}

Find the perimeter of the given triangle
trasher [3.6K]

Here it is given that the triangles ABP and DCR are similars, therefore we use the ratio rule which states that

corresponding sides of similar triangles are in same proprtion .

\frac{AB}{DC} = \frac{BP}{CR}

that gives

7/10 = BP/11

7*11=10BP

BP=7.7

Again using the ratio rule

\frac{AB}{DC} = \frac{AP}{DR}

7/10 = AP/6

42 = 10AP

AP = 4.2

Perimeter= AB+BP+AP = 7+7.7+4.2 = 18.9

Correct option is A.
