Answer:
x = 30 degrees
Step-by-step explanation:
These triangles are perfectly symetrical. This is shown by the length of sides given in the problem. Since the triangle is symetrical, E is equal to B just as D is equal to C. Since B is 30 degrees, we can tell that E is also 30 degree.
Answer:
The first term is 14.
Step-by-step explanation:
The general formula for this kind of sequence (arithmetic) is a(n) = a(1) + (n-1)c, where c is the common difference. Here, we have a(6) = -1 = a(1) + (6-1)(-3), or -1 +15 = a(1). The first term is 14.
