Step-by-step explanation:

27 + 3y = 90

3y = 90 - 27

y = 21

27 + (21×3) + x + 8x + 18 = 180 ( angles on a straight line sum up to 180)

9x + 108 = 180

9x = 180 - 108

9x = 72

x = 72/9

x = 8 degrees

Answer:

Y=21

X=8

Step-by-step explanation:

In the middle there is a right angle

therefore 27 +3y=90

Y will be 21

Then x+27+63+8x+18=180

x=8

Hence 8+27+3(21)+8(8)+18=180

Answer:

See below.

Step-by-step explanation:

Using the right triangle altitude theorem, the correct proportions are:

$\dfrac{AB}{AC} = \dfrac{AC}{AD}$

$\dfrac{AB}{x} = \dfrac{x}{AD}$

$\dfrac{25}{x} = \dfrac{x}{16}$

$x^2 = 25 \times 16$

$x = 20$

AC = 20 cm

$\dfrac{AB}{CB} = \dfrac{CB}{DB}$

$\dfrac{AB}{y} = \dfrac{y}{DB}$

$\dfrac{25}{y} = \dfrac{y}{9}$

$y^2 = 25 \times 9$

$y = 15$

CB = 15 cm

Rosita paid$27.08, including tax , for her family to eat dinner at a restaurant. She wants to tip a whole dollar amount that is

Bumek [7]

A reasonable tip would be $5.00

Rosita paid $27.08 an wants to tip a whole dollar closest to 20%.

The first step is therefore to find out 20% of $27.08.

= 20% x 27.08

= $5.42

The closest whole dollar depends on the first decimal point.

If it is 5 and above, the tip would be $5 as we would round down.

If it is 4 and below, the tip would be $6 as we would round up.

The first decimal is 4 so we would round down to $5.00

The tip would therefore be $5.00
