In ATUV, t = 900 inches, u = 830 inches and v=590 inches. Find the measure of ZU

Licemer1 [7]3 years ago

Answer:

To the nearest degrees, this is 64 degrees

Step-by-step explanation:

In triangle TUV, we want to get the measure of angle U

Since we have 3 sides, we can use cosine rule to get the measure of the angle facing one of the sides

Mathematically, we have that as follows;

u^2 = t^2 + v^2 -2tv Cos U

830^2 = 900^2 + 590^2 - 2(900)(590) cos U

-469200= -1062000 cos U

cos U = 469,200/1062000

cos U = 0.44181

U = arc cos 0.44181

U = 63.78 degrees

To the nearest degree, this is 64 degrees

coldgirl [10]

Answer:

15.9%

Step-by-step explanation:

Percent decrease formula =

(Initial value - New value/Initial value) × 100

Initial value = 9200kg

New value = 7739.4kg

Percent decrease = (9200 - 7739.4/9200) × 100

Percent decrease = (1460.6/9200) × 100

Percent decrease = 15.8760869565%

Approximately = 15.9%

The percent of decrease in the amount of strawberries used annually is 15.9%

Ivan

Answer:

In fact, the AB could be calculated in a quickest way, using Pythagorean theorem. In here, we try to use the property of trigonometry to work out AB.

Before applying trigonometry, in this right triangle we can calculate the remaining angle C:

C = 180 - 90 - A = 180 - 90 - 53.13 = 36.87 deg

We can use cosine formula, but here we use the sine formula for the sake of convenience. We have:

sine(angle measure) = ratio of opposite side over hypotenuse

In detail, sineC = AB/BC

Then, we have: AB = BC x sineC = 15 x sin(36.87 deg) = 9.000002 = ~9 ft

Hope this helps!

:)
