2) Use the law of sines to find the length of SR<br> sin⁡(A)/a=sin⁡(B)/b=sin⁡(C)/c

NeTakaya

Answer:

take 28 degree as reference angle

using sine angle

sin28=p/h

0.46=10/h

0.46h=10

h=10/0.46

h=21.73

therefore hypotenuse =21.73

again using sine rule

take 25 degree as reference angle

sin 25=p/h

0.42=SR/21.73

0.42*21.73=SR

9.12=SR

9.1=SR
