Answer:
<h2>SU = 3.5</h2>
Step-by-step explanation:
We have the triangle 30° - 60° - 90°.
Right triangles with 30-60-90 angles will have their ratio of the sides as
1 : √3 : 2 (look at the picture).
We have:
SR : SU : RU = 1 : √3 : 2
Therefore RU = 2SR and SU = SR√3.
We have RU = 4. Substitute:
2SR = 4 <em>divide both sides by 2</em>
SR = 2
SU = 2√3 ≈ 2(1.73) = 3.5

Answer:
6 < x < 51
Step-by-step explanation:
An acute angle has a measure between 0 and 90 degrees:
0 < 2x -12 < 90
12 < 2x < 102 . . . . . add 12
6 < x < 51 . . . . . . . . divide by 2
Possible values of x are between 6 and 51.
You have to plug in the numbers for x
