a)

b)

Step-by-step explanation:

Q11 a) ABCD is a parallelogram, then units.

Consider triangles AED and BEF. In these triangles

by reflexive property;

are corresponding angles formed when parallel lines BC and AD are intersected by transversal AE. By corresponding angles theorem, they are congruent.

By AA similarity theorem, . Similar triangles have proportional corresponding parts, so

ABCD is a parallelogram, then units, so

Q11b) ABCD is a parallelogram, then units. By segment addition postulate,

Consider triangles EBF and ECD. In these triangles,

by reflexive property

are corresponding angles formed when parallel lines AB and CD are intersected by transversal EC. By corresponding angles theorem, they are congruent.

So, by AA similarity theorem. Similar triangles have proportional corresponding parts, so

From the first equality,

From the second equality:

damm bro the struggle

step-by-step explanation:

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
