Step-by-step explanation:
ABC=DBC
(This will probably be a way more complex explanation than you need but it’s what I did.)
Okay so you know B=B because they’re both right angles. You know A=D because of the isosceles triangle theorem- if two sides of a triangle are congruent, then the angles opposite those sides are congruent. That leaves C=C. If B=B and A=D and all triangles add up to 180 degrees, C and C need to be the same.
2x² <span>- x + 8 = 0
D</span>iscriminant = b² - 4ac
a=2, b=-1, c=8
D = (-1)² - 4 * 2 * 8 = 1 - 64 = -63
