Answer:

see explanation

Step-by-step explanation:

When 2 chords intersect then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

4x = 16 × 7 = 112 ( divide both sides by 4 )

x = 28

Thus

diameter = LK = 4 + 28 = 32 cm

Answer:

x = 44.3°

Step-by-step explanation:

Redrawing the triangle,

To obtain x, we can apply the trigonometric relation :

Sin x = opposite / hypotenus

Opposite side = 6.5

Hypotenus = 9.3

Sin x = 6.5/9.3

x = sin^-1(6.5 / 9.3)

x = 44.34

x = 44.3°

In triangle JKL, if m

romanna [79]

Answer:

$\angle L = 52\\\\\angle J = 45\\\\\angle K = 83$

Step-by-step explanation:

$\angle J = \angle L-7\\\\\angle K=2\angle L-21\\\\\angle L = \angle L$

we know that

$\angle K +\angle J + \angle L =180$ by the sum of interior angles of a triangle

so we have

$(\angle L -7)+(2\angle L -21)+(\angle L)=180$

we can simplify

$(\angle L + 2\angle L + \angle L)+(-7-21)=180\\\\4\angle L -28=180\\\\4\angle L=180+28\\\\4\angle L = 208\\\\\angle L = 52$

and now we find the other angles

$\angle J = \angle L -7\\\\=52-7\\\\=45$

$\angle K = 2\angle L -21\\\\=2(52)-21\\\\=104-21\\\\=83$
