86. D. -10
87. H. -6, -3, 0, 2
88. Quadrant 1
Answer:
Option (B)
Step-by-step explanation:
By the theorem of the inscribed angle,
"An angle inscribed in a circle measures half of the central angle subtended by the same arc."
Since m(arc XY) = 52°
Angle subtended by the the arc at the center (Central angle) = m∠XWY = 52°
Measure of inscribed angle = m∠XZY
By theorem, m∠XZY = 
m∠XZY = 
= 26°
Therefore, Option (B) will be the answer.
136mm?? Isn't it 68 x 2 because Y-K and V-Y are the same, so 68 x 2=136? I don't know
Answer:
A. X=-3
Step-by-step explanation:
16x-4+5x=-67
21x=-67+4
21x=-63
Divide through by 21
X=-3
