Question

Find the value of x.

Answer 1

`\huge\bold{To\:find:}`

✎ The value of
`x`.

`\large\mathfrak{{\pmb{\underline{\orange{Solution}}{\orange{:}}}}}`

`\sf\purple{The\:value\:of\:x\:is\:10°. }`

`\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}`

Since it is right angle,

`Sum \: of \: angles \: = 90° \\ ⇢ 2x °+ 7x° =90 ° \\ ⇢9x° = 90° \\ ⇢x° = (90°)/(9) \\ ⇢x° = 10°`

`\sf\blue{Therefore,\:the\:value\:of\:x\:is\:10°.}`

`\huge\bold{To\:verify :}`

`2x° + 7x° = 90° \\ ➡ \: 2 * 10° +7 * 10° = 90° \\ ➡ \: 20° + 70° = 90° \\ ➡ \: 90° = 90° \\ ➡ \: L.H.S.=R. H. S`

Hence verified.
