Mathematics
1 answer:
Korolek [52]2 years ago
5 0

Step-by-step explanation:

If the figure is triangle then,

Let PR be x

So,

PQ+QR+PR= 180 (Sum of all the angles of the triangle)

Therefore,

6x+25+16-3x+x=180

4x+36=180

4x= 180/36

x= 144/4

X= 36

NOW,

PQ= 6x+25

= 6(36)+25

= 216+25 = 241= PQ.

QR = 16-3x

= 16-3(36)

= 16-108

= -92

PR = 36

hope it helps

Slav-nsk [51]

Answa line of symmetry will connect a vertex and a midpoint of an opposite side

it has 7-fold symmetry.  


Step-by-step explanation:

A line of symmetry is a line that we can use to "fold" a figure in half. In order to do this, we will "fold" the figure from a vertex to the middle of the side opposite the vertex. Since there are 7 vertices, there will be 7 lines of reflection. i looked it up so i hope this helps you can thank
