You find a number that can go to 180 and 12
2 b 3 c 4 e 5a 6 b 7 d it's the awnsers 2 thru 7
Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17
Step-by-step explanation:
Answer:
15.) BAD = 10. (Since AC is 8 and CD is 2 you'll add em together to form a right angle, and BAD is a right angle so therefore they are the same.)
16.) AB = 2. (CD is 2 so therefore AB is 2, Again same size...)
17.) BD = 8. (Same size as AC...)
