We have to choose which set of measures describes a quadrilateral that can not be inscribed in a circle. An inscribed quadrilateral has vertices that lie on a circle. The sum of the opposite angles of such quadrilateral is 180° ( the angles are supplementary ). Answer A: 103° + 77° = 180°, 69° + 111° = 180°. Answer B : 52° + 128° = 180°, 64° + 116° = 180°. Answer C: 42° + 136° = 178°, 64° + 118°=182° ( not complementary ). Answer D : 100° + 80° = 180° , 72° + 108° = 180°. Answer : C. 42°, 64°, 118°, 136°.<span> </span>

m=26 and s=16
Step-by-step explanation:
Answer:
a = 10, b = 5, c = 14, d = 25
Step-by-step explanation:
Plug in -2 for x ....
y = 2(-2)^2 + -2 + 4
y = 2(4) + 2
y = 10
Plug in -1 for x ....
y = 2(-1)^2 + -1 + 4
y = 2(1) + 3
y = 5
Plug in 2 for x ....
y = 2(2)^2 + 2 + 4
y = 2(4) + 6
y = 8 + 6
y = 14
Plug in 3 for x ....
y = 2(3)^2 + 3 + 4
y = 2(9) + 7
y = 18 + 7
y = 25
