Answer:
<em>The base of the triangle = 9inches</em>
Step-by-step explanation:
<u>Explanation</u>:-
The area of the triangle =
square units
Given area of the triangle(A) = 54 square inches
Given the height of the triangle (h) = 12 inches
now equating 

now simplification, we get
6 b = 54
Dividing '6' on both sides, we get
b = 9
The base of the triangle = 9 inches
<u>Conclusion</u>:-
<em>The base of the triangle = 9 inches</em>
Hey there!!
We know angle DEC = angle AEB
Hence,
... 4x + 12 = 5x - 10
... - x = - 22
... x = 22
4 ( 22 ) + 12
88 + 12
100° is the answer.
Hope my answer helps!
