Answer:

7√3 = x

Explanation:

Arbitrarily choose to focus on the 30 degree angle. Then the side opposite this angle is 7 and the side adjacent to it is x.

tan 30 degrees = (opp side) / (adj side), or (1√3) = 7 / x.

Inverting this equation, we get √3 = x/7.

Multiplying both sides by 7 results in 7√3 = x

Answer:


x =7√(3)

Explanation:

By definition, the tangent of a z-angle is defined as


tan(z) =(opposite)/(adjacent)

For this case


opposite = 7


adjacent = x


z=30\°

So


tan(30) =(7)/(x)


x =(7)/(tan(30))


x =7√(3)
