I think you would multiply 4 12/90 by 9 which equals 37 1/5
B - 45 because 27 divided by 6 is 4.5 and then 10x4.5=44
C - no 2 points can be on the same vertical line
Answer:
For the first one 25.925%
The second is 23.333%
The third is 27.27%
Let me know if this helps!
Answer:
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary, so ...
∠B +∠D = 180°
(3x -4) +(2x -6) = 180
5x = 190 . . . . . . . . . . . add 10, collect terms
x = 38 . . . . . . . . . . . . . divide by 5
∠D = 2(38) -6 = 70
∠B = 180 -70 = 110
The measures of angles B and D are 110° and 70°, respectively.
