Answer:If the questions consits of 36, 54, 72, and 108 it goes as 72 then 54
Step-by-step explanation:
Just did it on edgunity.
The measure of one of the congruent base angles in triangle ABC is 54degree.
What is the pentagoan?
A pentagon has five sides.
Therefore, we determine each of the central angles by dividing the given sum (360°) by 5.
[tex]=\frac{360}{5} =72^0[/tex]
This gives us the answer of 72 degree.
We let x be the congruent angles in the base and noting that the sum of the internal angles of the triangle is 180 degree,
we have the equation,
[tex]72 + x + x = 180^0[/tex]
[tex]2x=180-72\\2x=108\\x=\frac{180}{2} \\x=54^0[/tex]
The value of x from the equation is 54degree.
