Choose the triangle that seems to be congruent to the given one

We are given a figure with composite triangles.

We need to find a congruent triangle to triangle ADB.

Two figures are congruent if their corresponding sides and angles are congruent.

We can see

AB congruent to AB

AD congruent to BC and

AC congruent to BD.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
