Step-by-step explanation:
your x is 10 since its a parallelogram
u will have x and 5.6inch so u can find angle c
cos c= 5.6/10
c=55.9~56°
c + the red part to its left makes a 90° angle
we have c so to find red part 90-56=34°
then u have a triangle with 34° angle and a side of 9.8 inches u can find h then using sin
sin 34= h/9.8
h=5.48
