7x+55=90 angle in a rectangle is
7x=90-55 90
7x=35
x=35/7
x=5
The answer is 12cm because area (420) divided bye height (35) gives you the corresponding side 12cm.

Answer:
∠BDC = 46°
Step-by-step explanation:
Angle BDC intercepts arc BC, identified as having a measure of 92°. The angle's vertex, point D, is on the circle, so the angle is called an "inscribed angle." The measure of an inscribed angle is half the measure of the arc it intercepts.
∠BDC = (1/2)arc BC = 1/2(92°)
∠BDC = 46°
