I need help with the steps. The answer is (5,2)
Elden [556K]

So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

y+3+y=7\\2y+3=7\\2y=4\\y=2

Next, now that we have the value of y, substitute it into either equation to solve for x:

x+2=7\\x=5\\\\x=2+3\\x=5

<u>And this is how you get your final answer (5,2).</u>

Answer:

for Part A

Answer is C.

Step-by-step explanation:

\tan(a)  =  \frac{opposite}{adjacent }  \\

Here the angle, a is 60°, Opposite is 20 and adjacent is x.

Therefore we have,

\tan(60 )  =  \frac{20}{x}

Making x the subject gives us

x =  \frac{20}{ \tan(60) }

Part B
