Question

please tell the answer step by step​

Answer 1

Given:-

• Adjacent Angles of a Parallelogram are 3x+50° & 2x-20°.

Solution:-

$\boxed{\sf{☆\; Adjacent\;Angles\;of\;a\; Parallelogram\;are\; Supplementary (180°}}$

$→\;{\sf{(3x+50°)+(2x-20°) = 180°}}$

$→\;{\sf{3x+50°+2x-20° = 180°}}$

$→\;{\sf{5x+30° = 180°}}$

$→\;{\sf{5x = 180°-30°}}$

$→\;{\sf{x = 150°/5}}$

$→\;{\bf{x = 30°}}$

Angle 1 = 3×30°+50° → 140°

Angle 2 = 2×30°-20° → 40°

• Adjacent Angles are $\Large\red{\bold{140°}}$ & $\Large{\green{\bold{40°}}}$
