1. Yes.
Since, to be a triangle, the sum of the smallest two sides must be greater than the third side, the triangle can be formed.
3 + 22 > 24
2. This triangle is a right triangle.
180 - 60 - 30 = 90
90 degrees is a right angle.
Hope this helps!

As stated in the statement of the question, EF is a bisector of CD, so point G is the median point of CD, so CG = GD
5X - 1 = 7X - 13
X = 6
EF = EG + GF
6X - 4 = EG + 13 x = 6, so
6·6 - 4 = EG + 13
<h2>EG = 19</h2>

-5 - 12 = -17
Starts at -5 degrees, then it drops another 12, so you subtract 12 from -5.
The "period" of a repeating function is the change in x between consecutive identical values...in this case 3 units.
