Answer:

x=5, y=11

Step-by-step explanation:

> sum of interior angles of a polygon is (n-2)·180°, where n-is the number of sides, so our rhombus has sum of angles =(4-2)·180° =360°

>we know that the opposite angles are congruent so ...

>we have the sum of interior angles is

108+108+7y-5+7y-5 = 360, combine like terms

14y +206 =360, subtract 206 from both sides

14y = 154, divide both sides by 14

y= 11

>the sides are congruent therefore

4x+17 = 8x-3 , subtract 4x, and add 3 from both sides

17+3 =8x-4x, combine like terms

20 = 4x , divide by 4 both sides

5 =x

2 trig ratios missing sides and angels
ivanzaharov [21]

Answer:

D

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = \frac{adjacent}{hypotenuse} = \frac{13}{x} ( multiply both sides by x )

x × cos66° = 13 ( divide both sides by cos66° )

x = \frac{13}{cos66} ≈ 32.0 ( to the nearest tenth )

Is d y / d x the exact same as f ' ( x ) ? If yes, which is more commonly used?
Murrr4er [49]
It's dependent on the context. A book may ask you to find the f'(x) of a function and you may have to use a u sub in your problem which requires you to find the dy/dx of what you substitute. So in this case both would be used.

The judges at the track meet will award prizes to the top 4 teams. How many different ways can the top four teams place??
Nata [24]
They could give to teams more than likely on an average score the whole team has done, or at least that is what they are supposed to do. but they also might award the team which had more teammates get better places. for example if party place got three people on their team but they all did 3rd then boring barn who got 1 person could possibly win if that one person gets 1st place.

denis23 [38]

Answer:

It's the first option

Step-by-step explanation:

The Midsegment Theorem states that the segment connecting the midpoints of two sides of a triangle (in this case AB and  AC) is parallel to the third side (BC) and half as long.
