Answer:

  • SSS and SAS

Step-by-step explanation:

To use the law of sines we need to know two angles and one side or two sides and one angle which should be opposite to one of known sides.

  • SSS - <u>unable</u> to solve as no angle is known
  • AAS - two angles and non-included side, able to find the missing angle solve the rest
  • ASA - two angles and the included side, able to find the missing angle solve the rest
  • SAS- two sides and the included angle, <u>unable</u> to solve
  • SSA - two sides and non-included angle, able to find the other angles and solve fully

Answer:

  C.  168°

Step-by-step explanation:

The exterior angle at any vertex of an n-gon will be ...

  360°/n

So a 30-gon will have exterior angles of ...

  360°/30 = 12°

The adjacent interior angle is supplementary to this, so is ...

  180° -12° = 168°

_____

<em>Using the reasonableness test</em>

You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.

Victor is going to send some flowers to his wife. Dayton Florist charges $3 per rose, plus $12 for the vase. Tammy's Flowers, in
s344n2d4d5 [400]

Answer: the costs would be the same if he orders 29 rose flowers.

Step-by-step explanation:

Let x represent the number of roses that Victor would order such that the cost will be the same with either flower shop.

Dayton Florist charges $3 per rose, plus $12 for the vase. This means that if he orders x rose flowers, the total amount that he would pay is

3x + 12

Tammy's Flowers, in contrast, charges $2 per rose and $41 for the vase. This means that if he orders x rose flowers, the total amount that he would pay is 2x + 41

For the costs to be the same, the number of rose flowers that he orders would be

3x + 12 = 2x + 41

3x - 2x = 41 - 12

x = 29

6x+7y=5<br>2×-3y=7<br><img src="https://tex.z-dn.net/?f=6%20%5Ctimes%20%20%2B%207y%20%3D%205%20%5C%5C%202%20%5Ctimes%20%20-%203y
svetoff [14.1K]

Answer:

x=2; y=-1

Step-by-step explanation:

Hello,

(1) 6x+7y=5

(2) 2x-3y=7

We multiply equation (2) by 3, it gives

6x-9y=21 and we subtract from (1)

6x-9y-6x-7y=-16y=21-5=16

So y = -1

we replace in (1) 6x-7=5 <=> 6x=7+5=12 <=> x =12/6=2

thanks
