Question

Someone help me please

Answer 1

`27.13^o`

Explanation:

`\mathrm{Here,}\\a=28\mathrm{yd}\\c=23\mathrm{yd}\\\\\mathrm{Using\ the\ sine\ law,}\\\mathrm{(a)/(sinA)=(c)/(sinC)}\\\\\mathrm{or, }\ \frac{28}{\mathrm{sin22^o}}=\frac{23}{\mathrm{sin}C}\\\\\mathrm{or,sinC}=(23)/(28)\mathrm{sin22^o}=0.307\\\\\mathrm{or,\ C=sin^(-1)0.307=17.92^o}`
