Explanation:

∠4 = ∠1 & ∠2 = ∠3

360 - 2(98) = ∠2 + ∠3

∠3 = 164/2

∠3 = 82°

\huge\bold{Given :}

Angle 4 = 98°


\huge\bold{To\:find :}

The measure of angle 3.


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


\implies {\blue {\boxed {\boxed {\purple {\sf {∠\:3\:=\:82° }}}}}}


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

We know that,


\sf\pink{Sum\:of\:angles\:on\:a\:straight\:line\:=\:180°}

➪ ∠ 3 + ∠ 4 = 180°

➪ ∠ 3 + 98° = 180°

➪ ∠ 3 = 180° - 98°

➪ ∠ 3 = 82°

Therefore, the measure of ∠ 3 is 82°.


\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}

∠ 3+ ∠ 4 = 180°

✒ 82° + 98° = 180°

✒ 180° = 180°

✒ L. H. S. = R. H. S.


\boxed{Hence\:verified.}
