Question

2 adjacent angles of a parallelogram are in ratio 3:4 find all angles of parallelogram​

Answer 1

Answer:

Step-by-step explanation:

Since the adjacent angles in a parallelogram are supplementary.

3x+2x=180\degree3x+2x=180°

\Rightarrow5x=180\degree⇒5x=180°

\Rightarrow x=\frac{180\degree}{5}=36\degree⇒x=  

5

180°

​  

=36°

\therefore One\ angle\ =\ 3x\ =\ 3\times36\degree=108\degree∴One angle = 3x = 3×36°=108°

And another angle = 2x=2\times36\degree=72\degree2x=2×36°=72°
