\huge\bold{Given:}

Angle AOB = x + 4

Angle BOC = 3x + 2

Angle AOC =90° ( ∵ it is right angle )


\huge\bold{To\:find:}

The value of "x".


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


\longrightarrow{\blue{x\:=\:21°}}


\large\mathfrak{{\pmb{\underline{\purple{Step-by-step\:explanation}}{\purple{:}}}}}

Since it is right-angle,


Sum \: of \: angles \: = 90°


\longrightarrow{\green{}} x + 4 + 3x + 2 = 90°


\longrightarrow{\green{}} x + 3x + 4 + 2 = 90°


\longrightarrow{\green{}} 4x + 6 = 90°


\longrightarrow{\green{}} 4x = 90° - 6


\longrightarrow{\green{}} 4x = 84°


\longrightarrow{\green{}} x =
(84°)/(4)


\longrightarrow{\green{}} x = 21°


\sf\blue{Therefore,\:the\:value\:of\:x\:is\:21°.}

Now, the two angles are

∠ AOB = x + 4 = 21° + 4 = 25°

∠ BOC = 3x + 2 = 3 x 21° + 2 = 63° + 2 = 65°


\huge\bold{To\:verify :}

➡ ∠ AOB + ∠ BOC = ∠ AOC

➡ 25° + 65° = 90°

➡ 90° = 90°

➡ L. H . S. = R. H. S

Hence verified. ✔
