Question

Can someone pls give me the angles using the tangent^-1

Answer 1

9514 1404 393

Answer:

  ∠U = 60°

  ∠W = 30°

Step-by-step explanation:

The side length ratios are ...

  1 : √3 : 2

so you know this is one of the "special triangles." Its angle measures are 30°, 60°, and 90°. The smallest angle (W) is opposite the shortest side (7).

The angle measures are ...

  m∠U = 60°

  m∠W = 30°

[the UW measure is correct]

Your calculator can tell you the arctangent of √3 or 1/√3. Be sure to set it to degrees mode.
