How do I show my work for this question, I know it’s 11 but how?

ASB are congruent lengths

ARC are congruent lengths

BTC are congruent lengths

CT = 5 and we can use this to find RC by doing 13 - 5 which equals 8

so now we know that RA = 8

AS = 3

RA = 8

we can add these to get RS

8 + 3 = 11

so RS = 11

3+3+5+5+8+8= 32

Step-by-step explanation:

Step-by-step explanation:

Since this is a 2 variable equation system we will find the values of x & y by equaization.

x-5=-7x+11

x+7x=11+5

8x=16

x=16/8

x=2
