Aclass has fewer than 30 students exactly 2/3of the student's in the class own a football exactly 7/8 of the students in the class own football boots how many students are there in the class

This number would be 24. So 21 own football boots, 16 own a football and there are 24 children in the class.  not good at math so yeah

We require the congruence between another pair of corresponding angles to say that those triangles are similar by the Angle-Angle Postulate.

Step-by-step explanation:

To prove that the two triangles similar we can use these postulates:

Angle-Angle Postulate: if two pairs of corresponding angles between two triangles are congruent, then, those triangles are similar.Side-Side-Side Postulate: if all corresponding sides between two triangles are proportional, or they are in a same proportion, then, those triangles are similar.Side-Angle-Side Postulate: If two pairs of corresponding angles are proportional, and one pair of corresponding angles (which are formed by the proportional sides) are congruent, then, those triangles are similar.

So, in the problem, we know that one pair of corresponding triangles are congruent. Now, we require the congruence between another pair of corresponding angles to say that those triangles are similar by the Angle-Angle Postulate. That's the shortest way.
