Answer:
the answer might be 0.86 I don't know though
Answer:
More than half
Step-by-step explanation:
Half is 0.5 this is 0.785 approximately 0.280 more or > 0.5
Opposite angle of a quadrilateral add up to 180 degrees.
This means Angle A plus Angle C equal 180.
We can solve for X using that, then solve for Angle B.
2x-7 + x +4 = 180
Simplify:
3x -3 = 180
Add 3 to each side:
3x = 183
Divide both sides by 3:
x = 183 /3
x = 61
Now we know x, replace x with 61 in the equation for Angle B:
Angle B = 2x+3 = 2(61) +3 = 122 +3 = 125 degrees.

Hello!
The formula is given to you. :)
C = 3.14 • D (diameter; line across a circle that cuts it in half)
C = 3.14 • 21 = 65.94 inches.
Hope I helped! Also, I hope I didn’t answer this too late. ;)
