Answer:

Infinitely many triangles.

Step-by-step explanation:

We have a triangle ABC with measures of the angles as 70°,  90° and 20°.

Now, as we know that,

'The measures of the three angles of a triangle must be 180° '.

Moreover,

70° + 90° + 20° = 180°

Thus,many triangles can be made using these three angles.

Hence, with the given measurements of the angles, we can make infinitely many triangles.

Answer:

The correct answer option is: infinitely many triangles.

Step-by-step explanation:

We are given three measurements of angles and asked about how many different triangles can we make with these three angles.

We know that the sum of angles in a triangle is always equal to 180 degrees.

20° + 70° + 90° = 180°

So we can use the same measure of angles but change the measure of side lengths. Therefore, we can make infinitely many triangles by varying these measurements of sides.
