Using the technique in the model above, find the missing sides in this 30°-60°-90° right triangle.
nydimaria [60]
For this case what you should do is use the following trigonometric relationship:
 tan (x) = C.O / C.A
 Where
 x: angle
 C.O: opposite leg
 C.A: adjoining catheto
 Substituting the values we have:
 tan (60) = long / short
 tan (60) = long / 2
 long = 2 * tan (60)
 long = 3.46
 Answer: 
 long = 3.46

X=70, y=55

The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.

Then use the triangle angle sum theorem and set the equation to 180.

55+55+x=180
110+x=180
x=70

The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.
