kicyunya [14]3 years ago
5 0

Answer:

3 units

Step-by-step explanation:

By intersecting chords theorem:

AE \times EB = CE \times ED

\therefore 3 \times 4= x \times (x+1)

\therefore 12= x^2 +x

\therefore  x^2 +x-12=0

\therefore  x^2 +4x-3x-12=0

\therefore  x(x +4)-3(x+4)=0

\therefore  (x +4)(x-3)=0

\therefore  (x +4)=0, \: (x-3)=0

\therefore  x=-4, \: x=3

Since, the value of x can not be negative.

\therefore x\neq - 4

\implies x = 3

\implies CE = 3

Find the missing lengths: LK=15 and KH=9, find KI and HI.
Luda [366]

Answer:

KI=11.25 and HI=6.75

Step-by-step explanation:

Consider the below figure attached with this question.

According to Pythagoras Theorem:

base^2+perpendicular^2=hypotenuse^2

Use Pythagoras in triangle HKL

LH^2+KH^2=LK^2

(LH)^2+9^2=15^2

(LH)^2+81=225

(LH)^2=144

Taking square root on both sides.

LH=12

Let length of HI be x.

LI = 12+x

Use Pythagoras theorem in ΔKLI,

(KI)^2+15^2=(12+x)^2

(KI)^2+225=x^2+24x+144

(KI)^2=x^2+24x+144-225

(KI)^2=x^2+24x-81...(1)

Use Pythagoras theorem in ΔHKI,

(KI)^2=x^2+9^2

(KI)^2=x^2+81...(2)

From (1) and (2) we get

x^2+81=x^2+24x-81

24x=162

x=\dfrac{162}{24}=6.75

Hence, the measure of HI is 6.75 units.

Substitute x=6.75 in equation (2).

(KI)^2=(6.75)^2+81

(KI)^2=126.5625

Taking square root on both sides.

KI=\sqrt{126.5625}

KI=11.25

Hence, the measure of KI is 11.25 units.

What attributes help you tell the difference between a rhombus and a rectangle? Explain.
goblinko [34]
The angles will help you tell the difference. In a rectangle, all angles are 90 degrees. In a rhombus, the 2 opposite facing angles are the same and all side lengths are the same. 
Hope I helped. :P
