E) Infinite
d) only 3​

Answer 1

Step-by-step explanation:

according to me answer can be....

only one

Answer 2

Infinite triangles are possible having 60° , 90° and 30°.

• The angles of the prescribed triangle are 60°,30° and 90° which makes 180°,when we combine them. So,it will be a valid triangle if we go with the given angles.

• Now, moving on, there is no description about the lengths of the side of the triangle.

• So,we can draw infinite number of triangles which have infinite combination of the lengths of the three sides by maintaining the given angle ratio.

• So,the number of possible triangle is infinite.
