QS = 10 cm

QRS = 40cm

Step-by-step explanation:

4x + 1 = 5x

x= 1 cm

QS = 4x + 1 + 5x

= 9x + 1

= 9 + 1

= 10cm

QRS perimeter

QS + RQ + RS but ( RQ = RS)

= 10 + 15 + 15

= 40cm

That is a isosceles triangle, therefore x and the top angle are the same.

There’s 180 degrees in a triangle.

Therefore:

(180 - 38)/2 = x
142/2 = x
71 = x
