Question

$\frac{2}{5} \div \frac{1}{2} =$
4.Two obtuse angles can form a linear pair​

Answer 1

Answer:

No

Step-by-step explanation:

We know obtuse angles are angles whose sum is greater than 90°. So let's take three pairs of obtuse angles of any degree. Hence, we can say that two obtuse angles cannot form a linear pair.

Answer 2

1) $= \frac{2}{5} \div \frac{1}{2}$

$= \frac{2}{5} \times \frac{2}{1}$

$= \frac{4}{5}$

2) No
