Because the 2 sides of the triangle are the same, they are both 21, the two bottom angles would also be the same.
The 3 inside angles of a triangle must equal 180 degrees.
The top angle is given as 38, so the remaining two angles must equal 180 - 38 = 142 degrees.
Since the 2 bottom angles would be the same, divide 142 by 2 to get x.
X = 142 / 2 = 71 degrees.
Answer:
8.56
Step-by-step explanation:
Hello!
First, let's write an equation for the problem.

Now, all you have to do is solve it.

=
16Each side is 16 meters. I hope this helps!
The true statement about the sequence of transformations is it includes exactly two rigid transformations.
<h3>How to determine the true statement?</h3>
The transformation statement is given as:
a sequence of transformations that rotates an image and then translates it in order to map it onto another image
This can be split as follows:
- A sequence of transformations that rotates an image
- Then translates it in order to map it onto another image
Translation and rotation are rigid transformations
This means that the size and the angle of the shape that is transformed will remain the same
Hence, the true statement about the sequence of transformations is it includes exactly two rigid transformations.
