Type SSS SAS ASA AAS or HL to justify why the two larger triangles are congruent

HL

Step-by-step explanation:

We know the following:

The hypotenuse, DB, of ∆BAD is congruent to the hypotenuse, CA, of ∆CBA.

Also, a leg, AB in ∆BAD is congruent to a leg, AB in ∆CBA.

This shows that the hypotenuse and a leg of ∆CBA is congruent to the hypotenuse and the corresponding leg of ∆BAD. Based on the Hypotenuse-Leg Theorem, both triangles are congruent.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
