So, we need to consider what is being done.

So, lets start with the -3.

-3*

Now, lets see what's next

2 times a number is the same as saying 2x, then add one.

That is equal to five.

-3(-2x+1)=5

Now,

6x-3 = 5

6x = 8

x= 8/6

Someone help please this is for trigonometry

Softa [21]

Hi there!

Something really good to remember about trigonometry is SOHCAHTOA. I won’t dive into too much detail about it, but you should google it for future assignments.

Anyways,

tan50°=14/AB
ABtan50°=14
AB=14/tan50°
AB=11.75

cos50°=14/AC
ACcos50°=14
AC=14/cos50°
AC=21.78

For the measure of angle C you can use a theorem called the third angle theorem. In every single possible triangle, the sum of all three angles adds up to 180°. You can set up an equation like so...

angleC=180-(90+50)
angleC=180-140
angleC=40°

iren2701 [21]

Answer:

x=10, y=6

Step-by-step explanation:

the send equation minus the first.

(5x+y)-(3x+y)=56-36

2x=20--->x=10

then put x=10 to the first equation, 3*10+y=36, get y=6
