Answer:
D. 8
Step-by-step explanation:
The given diagram is a trapezium. We know that the consective sides of a trapezium are equal. so,
Putting the values of consecutive sides equal:
So, KI will be equal to LI
3x-7 = x+3

Putting the value of x in the equation of KI
3x-7
=3(5)-7
=15-7
=8
Hence, the correct answer is D. 8 ..
Answer:
y° = 7°
Step-by-step explanation:
(8y +4) +(8y +4) +(8y +4)=180° ( Equilateral Triangle)
24y +12= 180°
24y= 180-12
y=7°
