k = 10
Step-by-step explanation:
the sum of any two interior angles is equal to the exterior angle of the unknown interior angle
4k+5 + 6k+10 = 115
10k + 15 = 115
10k = 100
k = 10
By definition, the area of the trapezoid is:
A = (1/2) * (AB + CD) * (h)
Where,
AB, CD: bases of the trapezoid
h: height
Substituting values:
A = (1/2) * (19 + 19) * (14)
A = 266 units ^ 2
Answer:
The area of the special trapezoid is:
A = 266 units ^ 2
