Step-by-step explanation:
Hello! I hope you are having a nice day!
We can solve this problem in two steps; solving and theory.
I'll go and start off with the theory part!
Theory
We know that in geometry there are many types of triangles that have various different angles. With that, there are a few special triangles that people have made formulas for, one being a 30, 60, and 90 degree triangle.
The theorem states that the hypotenuse is
, the side opposite to 60 degrees is
, and the bottom is
.
Solving
We can solve this problem in a step, we just need to know what the theorem said and implement it here, since we know the values of the sides of the triangle, we can solve it by finding out the opposite side and applying the theorem rules.
If we look at the graph, we can see that the
part of the side opp. of 60 degrees is 4, that means that
would be double of 4, which is 8.
Therefore your answer would be: 
Cheers!

Answer:
Trapezoid
Step-by-step explanation:
The two sloped opposite sides are congruent. The two uncongruent opposite sides are parallel. There are no right angles. You can do this by finding the distance and slopes of the lines.
Not triangle because has four vertices.
Answer:
a:x=-3
c:x=1
Step-by-step explanation:
The zeros of a function are the values of x for which the value of the function f(x) becomes zero.
In this problem, we have the following function:

Here we want to find the zeros of the function, i.e. the values of x for which

In order to make f(x) equal to zero, either one of the factors
or
must be equal to zero.
Therefore, the two zeros can be found by requiring that:
1)

2)

So the correct options are
a:x=-3
c:x=1
