Answer:
K = 97 degrees
Step-by-step explanation:
The four interior angles of a quadrilateral is always equal to 360 degrees.
127 + 88 = 215
(10x + 7) + (5x + 3) = 15x + 10
360 - 215 = 145
145 = 15x + 10
130 = 15x
9 = x
k = 10x + 7
k = 10(9) + 7
k = 97
Fifty five percent times two hundred and sixty equal one hundred and forty three
Its alot of long division, but the answer is 217.625.
