<h2>The missing measures of the angles are:</h2>
<u>Given</u>:
<em><u>Note the following:</u></em>
- An equilateral triangle has all its three angles equal to each other. Each angle =
.
- This implies that, since
is equilateral, therefore, 
- Base angles of an isosceles triangle are congruent to each other.
- This implies that, since
is isosceles, therefore, 
Applying the above stated, let's find the measure of each angle:
- Find
(an angle in an equilateral triangle equals 60 degrees)
- Find
- Find
and 
(base angles of isosceles triangle WZY)
(base angles of isosceles triangle are congruent)
Therefore,
- Find
Substitute
The missing measures of the angles are:

The correct answer is A, if you use photomath you can usually find the answers to most algebra problems
Answer:
-3
Step-by-step explanation:
area = width * length
or
A = W * L
55 = W * (W+6)
solve for width:
0 = W^2 + 6W - 55
this is a quadratic and has two solutions -11 and 5
a length can only be non-negative so discard -11.
width W = 5 miles
now the length is 5+6 = 11 miles
