Jharne De and Ranjana Kumar Solutions for Chapter: Lines and Angles, Exercise 6: Test Paper 2

The supplement of an acute angle is always a/an_____angle.

The complement of $56°$ is $k°$. The value of $k$ is _____.

Write the value of $y$ without the degree symbol.

In the figure given below, $l\parallel m$ and $n$ is a transversal. Value of $y=\_\_\_\_\_°$.

Find the numerical value of $m$ in the figure given below:

In the figure, the arms of the two angles are parallel. If $\angle ABC=72°$ ,$\angle DEF=\_\_\_\_\_°$.

Prove that lines $l$ and $m$ are parallel to each other in the following figure.

In the given figure, $\angle ABE=15°,\angle ABD=80°,\angle EBC=75°$,$\angle DBC=\_\_\_\_\_°$.
