Answer:

x | -7 -5 -3

y | -21 -15 -9

Step-by-step explanation:

y = 3x

If x = -7 then y = 3 × (-7) = -21

x = -5 then y = 3 × (-5) = -15

x = -3 then y = 3 × (-3) = -9

Answer:

7. x = 5

8. x = 2, y = 6

9. x = 21, y = 39

Step-by-step explanation:

For a parallelogram, the lengths across intersection are equal.

7. For a parallelogram, the lengths across intersection are equal.

So that,

3x = 4x - 5

4x - 3x = 5

x = 5

8. For a parallelogram, the lengths across intersection are equal.

So that,

2x = 4

x = $\frac{4}{2}$

x = 2

and

y - 1 = 2y -7

7 - 1 = 2y - y

y = 6

x = 2, y = 6

9. For a parallelogram, opposite angles have equal value.

Thus,

3x = (4x - 21)

3x = 4x - 21

x = 21

and

3y = (y + 78)

3y = y + 78

3y - y = 78

2y = 78

y = $\frac{78}{2}$

= 39

y = 39

x = 21, y = 39

use the picture to write each ratio as a simplified fraction (how are you going to find the length of the third side?) show your

Butoxors [25]

Answer:

<h3>See below</h3>

Step-by-step explanation:

to figure out the ratios we must figure out the length of hypotenuse first to do so we can consider Pythagoras theorem given by

$\displaystyle {a}^{2} + {b}^{2} = {c}^{2}$

$\displaystyle \implies c = \sqrt{ {a}^{2} + {b}^{2} }$

substitute:

$\displaystyle c = \sqrt{ {12}^{2} + {9}^{2} }$

simplify squares:

$\displaystyle c = \sqrt{ 225 }$

simplify square root:

$\displaystyle c = 15$

now recall that,

$\displaystyle \sin( \theta) = \frac{opp}{hypo}$
$\displaystyle\cos( \theta) = \frac{adj}{hypo}$
$\displaystyle \tan( \theta) = \frac{opp}{adj}$

the ratios with respect to angle w given by

$\displaystyle \sin( W) = \frac{12}{15} = \frac{4}{5}$
$\displaystyle \cos(W) = \frac{9}{15} = \frac{3}{5}$
$\displaystyle \tan( W) = \frac{12}{9} = \frac{4}{3}$

the following ratio with respect to angle X

$\displaystyle \sin(X) = \frac{9}{15} = \frac{3}{5}$
$\displaystyle \cos(X) = \frac{12}{15} = \frac{4}{5}$
$\displaystyle \tan( X) = \frac{9}{12} = \frac{3}{4}$
