Remark
Good thing you tried to answer the question. At lease we know how to proceed.
A is wrong, because you can draw a conclusion.
B Remember that CD is constructed so that AB is cut in half. So the distance from CD to B is the same distance as CD to A. Choice B is true.
C is incorrect. CD can be extended to any length as long as CD goes through the point where the two arcs above and below AB meet are joined by C and D, then CD can be any length. In order words, CD can be any length.
D Doesn't have to be. See the answer for C.
Answer:
Step-by-step explanation:
TQRS is an inscribed quadrilateral.
5 x - 52° + 3 x + 40° = 180°
8 x - 12° = 180°
8 x = 180° + 12°
8 x = 192°
x = 192° : 8 = 24°
m∠ R = 3 · 24° + 40° = 112°
m∠ T = 5 · 24° - 52° = 68°
m∠ S = 360° - ( 68° + 68° + 112° ) = 112°
Answer:
m∠R, m∠S, m∠T = 112°, 112°, 68°.
18r^2 - 24r + 42. When you want to express something as squared or with an exponent you put ^ this symbol then the number(s)
