Answer:

1, 2, 3, 6

Step-by-step explanation:

I don't really know how to explain this but if the only change between the two triangles is that it was reflected, then there was no change of any of the angles or side lengths, you just have to make sure you match up the rights angles and the right sides.

What is the value of x

Gemiola [76]

9514 1404 393

Answer:

x = 10

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation ...

Sin = Opposite/Hypotenuse

sin(30°) = 5/x

Solving for x, we get ...

x = 5/sin(30) = 5/0.5

x = 10

_____

It can be helpful to remember that the side ratios in a 30°-60°-90° triangle are ...

1 : √3 : 2

That is, the hypotenuse is 2 times the length of the side opposite the 30° angle. Here, that means x = 2×5 = 10, as we found above.

What number would you multiply the 2nd equation by in order to eliminate the y terms?

leonid [27]

Answer:

x=3

y=-1

Step-by-step explanation:

first multiply the 2nd row by 2 so you will get

4x-4y=16

4x+2y=10

then subtract the 2nd row from the first row and so you will get

-6y=6

then solve for y in the above equation

y=-1

then substitute y=-1 into any 2 equations .

i picked the first 1

4x-4 × -1=16

then solve for x .

you will get

x=3

Answer:

$\frac{7}{2}$

Step-by-step explanation:

$\frac{3! + 0!}{2! \times1! } = \frac{(3 \times 2 \times 1) + 1}{(2 \times 1) \times 1} = \frac{6 + 1}{2} = \frac{7}{2}$
