Answer 1

Explanation:

`\sf{\bold{\blue{\underline{\underline{Given}}}}}`

`\tt{\angle{c}=110°}`

and,

`\tt{BC=AC}`

`\sf{\bold{\red{\underline{\underline{To\:Find}}}}}`

☆Find the
`\angle{B} ~and~\angle{A}`

`\sf{\bold{\purple{\underline{\underline{Solution}}}}}`

Here,

BC =AC

so,

⠀⠀⠀

`\angle{A}=\angle{B}`

we know that,

`\tt{\boxed{\pink{\angle{A}+\angle{B}+\angle{C}=180°}}}`

But
`\angle{C}=110°`(Ģìvéñ)

so..

`\angle{A}+\angle{B}+110°=180°`

`\angle{A}+\angle{A}+110°=180°`

`\because{\angle{A}=\angle{B} }`

`2\angle{A}=180°-110°`

`2\angle{A}=70°`

`\angle{A}=(70°)/(2)`

`\boxed{\orange{\angle{A}=35°}}`

But...

`\angle{A}=\angle{B}`

soo,

`\boxed{\orange{\angle{B}=35°}}`

`\sf{\bold{\green{\underline{\underline{Answer}}}}}`

⠀⠀⠀⠀

`\boxed{\green{\angle{A}=35°}}`

`\boxed{\green{\angle{B}=35°}}`
