Step-by-step explanation:

sinB=  

hypotenuse

opposite

=  

72

29

\sin B = \frac{29}{72}

sinB=  

72

29

B=\sin^{-1}(\frac{29}{72})

B=sin  

−1

B=23.752\approx 24^{\circ}

B=23.752≈24

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
