Question

Q.1 The measure of two angles of a parallelogram is in the ratio of 3: 2. Find the measure of each
of the angles of a parallelogram.
​

Answer 1

Answer:

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°

Answer 2

Answer:

parallelogram is another pair of opposite sides are equal and parallel
