Answer:

(~1.6,~-8.6)/(1.599,-8.597)

Step-by-step explanation:

This uses the system of equations, if you'd like to find more examples. First, let's mess with the first equation and solve for the easiest findable variable.

1. 3x+8y = -13 -> x = (-13-8y)/3 & y = (-13-3x)/8

2. Using the x equation because it's easier to use when entering into the second equation, we can get 14(-13-8y/3)

(-182-112y)/3 = -10 = 3y/5 is then our new eqn,

Then, we can make the fractions on the right and left equal and find y

9y/15 = -910-560y/15 ->

9y = -910-560y

569y = -910

y = 1.599

3. Now, insert 1.599 into the first x equation we made, x = (-13-8y)/3

to get x = -8.597

4. Your solution is 1.599, -8.597 or ~1.6,~-8.6

Somebody help me please and thank you

Answer:

4√3

Step-by-step explanation:

Use the acronym SOH CAH TOA and pick your angle. Im gonna pick the 30 degree angle. From the 30 degree angle, the x side is the hypotenuse, and the 2√3 is the opposite. I need to find H and O, which is the SOH part of my acronym.

Therefore Sin 30 = O/H. Then SIN 30 = 2√3/x.

We multiply both sides by x ⇒ x × sin 30 =2√3

Lastly we divide by sin 30. x = 2√3/ sin 30

We know that sin 30 is 1/2.

2√3 ÷ 1/2 (keep change flip) ⇒2√3 ×2 ⇒4√3

Sin 30 is equal to
