I WILL AWARD BRAINLIEST!! PLEASE HELP!!
Anastasy [175]

Answer:

m∠EBC=65° 15' and AC=20in

Step-by-step explanation:

Given:

AB≅BC

AE=10in\\m\angle FEC=90\\m\angle ABC=130\°30'

From the given Data, we can conclude the following:

1. Since two sides of the triangle ABC are congruent, therefore its an isosceles triangle.

2. m\angle FEC=90°. This shows that the line BE is perpendicular to AC. By property of isosceles triangle, the line which passes from the vertex of the largest angle of triangle and cuts the opposite side(base) perpendicularly is the perpendicular bisector of the side and angle bisector of the angle.

∴  m\angle EBA\ ≅m\angle EBC    [ Definition of Angle bisector]

m\angle ABC=130\°30'

m\angle EBC=\frac{m\angle ABC}{2}=\frac{130\°30'}{2}=65\°15'

m\angle EBC=65\°15'

∴AE=EC       [ Definition of perpendicular bisector]

AE=EC=10in

AC=AE+EC

AC=10+10=20in

AC=20in

Quadrilateral FGHI is similar to quadrilateral JKLM. Find the measure of side JK
Stells [14]

Answer:

Heyyyy!!

The answer is 66.9

please read the explanation... it will help... I promise

Step-by-step explanation:

Okay... Here we go...

The context mentions that the two quadrilaterals are similar... meaning their sides are proportional...

So... you basically have to find the scale factor...

(the math itself is easier than the explanation...

51/16 = 3.1875 (that is the number we multiplied the sides of quadrilateral FGHI to get quadrilateral JKLM...

so to get side JK all you have to do is multiply that scale factor by side FG... which after the use of a calculator results in 66.9 (i rounded, and used a calculator... lol)

but yeah... i hope this helps...
