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.
Answer:
Big square - unshaded = shaded
((8+4)X(10+5))-(10X8)=100
Answer: 100

Answer:
trapezoid
Step-by-step explanation:
y = 4x slope = 4
y' = 4x -16 slope = 4
TA // OM
TA: -1 ≤ x ≤ 0 (limited value)
OM: 3 ≤ x ≤ 5
TA and OM limited in different range, their length is not equal
The shape is a trapezoid
89/52 = 1.71153846 = 1R 37
43/36 = 1.19444444 = 1R 7
