We have to determine if triangle PQR is similar to triangle XYZ or not.

To determine if the two triangles are similar, we use three postulates

AA, SSS, SAS.

AA means two angles must be equal in both triangles.

From picture we can see that only one angle is given so we can't be sure about other angles.


SSS means all sides are in same ratio but we have been given value of only one side. So that is also not applicable.


SAS means ratio of two sides from both traingles is equal and both triangles share a common angle but that is also not the given case.


Hence final answer is D. "Cannot be determined".

Answer: SAS similarity theorem

Build proportional relation:

\Rightarrow \sf \dfrac{AC}{BC}  = \dfrac{EC}{DC}

\Rightarrow \sf \dfrac{200}{150}  = \dfrac{320}{240}

\Rightarrow \sf \dfrac{4}{3}  = \dfrac{4}{3}

  • So, the given that <u>two sides are congruent</u> and <u>one angle equal</u>.

Theorem followed: SAS similarity theorem

Can someone please help me with this question
Liono4ka [1.6K]

Answer:

m = 9

Step-by-step explanation:

1) Find scale factor

12/8 = 3/2 = 1.5

2)  6x1.5 = 9

OR

1) Set up proportion -> 6/8 = m/12

2) Cross multiply -> 8m = 72

3) Divide both sides by 8

4) m = 9

A side of the triangle below has been extended to form an exterior angle of 128°. Find the value of x.
hjlf
First you take the 128 and subtract it from 180. You then take the angle that’s vertical from it and place the number (52) and you add 52 + 24 to get 76. After that you take 76 and subtract it from 180 to get 104. X=104
