40) -31
41 ) 19
this are the answers I think
We have that since the chords are equal, the arcs are equal too. Hence AB=RS. We also have that AB=AR+RB and RS=RB+BS. By equating these two, we have that AR=BS. Hence BS=55 degrees. Substituting back, since we know RB and BS, we get: RS=55+66=121 degrees
Hi do you still need help? :)
Length = x
width = y
2x + 2y = 32
x - y = 4
x = 4 + y
2(4+y) + 2y = 32
8 + 2y + 2y = 32
4y = 24
y = 6 cm (width)
x = 4 + 6
x = 10 cm (length)
