The sum of the angles of a quadrilateral is 360°.

Given that x=30, the measure of ∠C is
∠C = (5/2)×30 +40 = 115
The appropriate choice is ...
D) 115°
Part A: 7/10 because .7 represents 70/100 of a whole, or 7/10.
Part B: I think 1 and 89/100 because 89/100 represents that fraction
These are my answers, so I may be wrong.
Hope I helped, and good luck!
