Mathematics
1 answer:
ZanzabumX [31]3 years ago
4 0

Answer:

Step-by-step explanation:

let ABCD be cyclic parallelogram.

Then ∠A=∠C

as it is cyclic so ∠A+∠C=180

∠C+∠C=180

2∠ C=180

∠C=90

So ∠A=90

similarly ∠B=∠D=90

so it is a rectangle.

Answer:

x = 31.2

Step-by-step explanation:

\frac{1}{2}x - 19.7 = -4.1

\frac{1}{2}x = 15.6 --- add 19.7 to both sides to get rid of -19.7

x = 31.2 --- multiply both sides by 2 to get rid of \frac{1}{2}
