Find x round to the nearest tenth! trigonometry question! !

x = 466.7 ft

Step-by-step explanation:

The top left angle of the triangle is 59°, we know because we are shown that the exterior angle outside that part of the triangle is 31°, so 59° would make that a corner.

We can use Sin of this angle to find the missing side (in this case, the hypotenuse)

Sin 59° = 400/x

Solve for x

x(Sin 59°) = 400

  x = 400/(Sin 59)

    x = 466.7    (rounded to the nearest tenth)
