Question

Can anyone help me with this?​

Answer 1

• Find height first
• Let height be p

`\\ \rm{:}\rightarrowtail tan50=(p)/(12)`

`\\ \rm{:}\rightarrowtail p=12tan50`

`\\ \rm{:}\rightarrowtail p=12(1.19)=14.3`

Now

Area=

• 1/2×Base×Height

`\\ \rm{:}\rightarrowtail (1)/(2)(12)(14.3)=6(14.3)=85.8cm^2`
