Answer:

60 x 130

Step-by-step explanation:

____

| |

w+70 | | w+70

| |

---------

add all the sides

2(w+70)+2w=380

2w+140+2w=380

4w+140=380

move the 140 to the other side of the =

4w=380-140

4w=240

divide both sides by 4

w=60

to get the length plug in 60 to w+70 to get 130 and width is just 60.

Round Ed to the nearthest tenth and answer now question

Vikki [24]

Answer:

$y = 9.1$

Step-by-step explanation:

y can be found using the Law of sines as explained below:

m < Y = 106°

m < X = 58°

WY = x = 8

WX = y = ?

Thus,

$\frac{x}{sin(X)} = \frac{y}{sin(Y)}$

$\frac{8}{sin(58)} = \frac{y}{sin(106)}$

$\frac{8}{0.848} = \frac{y}{0.961}$

Multiply both sides by 0.961 to solve for y

$\frac{8}{0.848}*0.961 = \frac{y}{0.961}*0.961$

$\frac{8*0.961}{0.848} = y$

$\frac{8*0.961}{0.848}*0.961 = y$

$9.07 = y$

$y = 9.1$ (to the nearest tenth)
