Answer:

x = 6

Step-by-step explanation:

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

2x = 3 × 4, that is

2x = 12 ( divide both sides by 2 )

x = 6

Quadrilaterals ABCD and PQRS shown below are two similar figures.<br>Find the values of x and y.​
nadezda [96]

Answer:

x = 12, y = 16

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{AD}{PS} = \frac{DC}{SR} , substitute values

\frac{20}{2x+6} = \frac{18}{27} ( cross- multiply )

18(2x + 6) = 540 ( divide both sides by 18 )

2x + 6 = 30 ( subtract 6 from both sides )

2x = 24 ( divide both sides by 2 )

x = 12

-------------------------------------------

and

\frac{AB}{PQ} = \frac{DC}{SR} , substitute values

\frac{y}{24} = \frac{18}{27} ( cross- multiply )

27y = 432 ( divide both sides by 27 )

y = 16

Please help. Explain how.

Answer:

y = \frac{4}{3} x +1

Step-by-step explanation:

1: find the perpendicular gradient - this is the negative reciprocal of the original gradient:

y=\frac{-3}{4}x+ 2 \\y=\frac{4}{3} x+c

2: Substitute in the coordinate to find the value of c:

y=\frac{4}{3}x +c\\5 = \frac{4}{3} (3) + c\\5 = 4+c\\c=1

3: Put it all together:

y=\frac{4}{3}x+1
