Use the figure to the right to find the missing lengths of the triangle.
pychu [463]

To find AB(x) and BC(y), you can do(there are multiple ways you can do this):

tan A = \frac{y}{7}

tan 60° = \frac{y}{7} or (tan 60°) · 7 = y

tan 60° = \frac{\frac{\sqrt{3} }{2} }{ \frac{1}{2} } = \sqrt{3}

√3 · 7 = y

7√3 cm = y


sin B = \frac{7}{x}

sin 30° = \frac{7}{x} or x= \frac{7}{sin 30}

sin 30° = \frac{\frac{1}{2} }{1} = \frac{1}{2}

x = \frac{7}{\frac{1}{2} } = 14

x = 14 cm


AB = 14cm

BC = 7√3 cm

How to solve using Substitution or Elimination?<br> y=3x-1<br><br> y=2x+2
n200080 [17]

By elimination:

y = 3x - 1

y = 2x + 2

Subtract the second equation from the first

0 = x - 1

y = 2x + 2

Subtract the first equation from the second

0 = x - 1

y = x + 3

Subtract the first equation from the second again

0 = x - 1

y =      4

Subtract x from both sides of the first equation

- x =  - 1

y =      4

Divide the first equation by (-1)    

x =  1

y =  4

<h3>So, the solution is  x = 1  and  y = 4   {or: (1, 4)}</h3>
