I started this one then got busy with other things.


z and 71 deg form a same side interior pattern


they're supplementary angles


sum to 180 degrees


z + 71 = 180


z = 180 - 71


z = 109 degrees


z and x are alternate angles


their measures are the same


z = 109 deg so x = 109 deg


y and 71 deg form adjacent angles which are supplementary


sum to 180 degrees


y = 180 - 71 = 109 deg


x = 109 deg, y = 109 deg, z = 109 deg


Part b


w and 88 form a supplementary pair


they add to 180 deg


w = 180 - 88 = 92 deg


v and 101 deg are vertical or opposite angles


They are congruent


So v = 101 deg

A new homeowner needs to put up a fence to make his yard secure. the house itself forms the south boundary and the garage forms
Eva8 [605]

Let the width = x feet, then the length = 160 - x  feet.

The area =  x * (160 - x) = 4000

160x - x^2 = 4000

x^2 - 160x + 4000 = 0

x =  [- (-160) +/-  sqrt (160^2 - 3 * 1 * 4000)] / 2

x =   128.98 or 31.01

answer is length = 129 feet and width = 31 feet   ( to nearest foot).

A horse ran 800 m in 40 seconds 1200 m in 60 seconds in 480 m and 24 seconds is this a proportional relationship if so what is t
Naddik [55]

Answer:

Yes this is a proportional relationship.

Equation is;

D=20T

Step-by-step explanation:

A horse run;

800m in 40 seconds

1200m in 60 seconds

and

480m inn 24 seconds

800m ÷ 40s = 1200m ÷ 60s = 480m ÷ 24s = 20

The equation here is Distance(D) = 20 × Time(T)

D=20T

It implies that the distance of the horse is directly proportional to the time it takes to run.
