Answer:
x^2 − 20x + 100
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
3 times 14 equals 42, and 42 divided by 2 is 21. 21 divided by 3 is 7. :)
2 .............:)
Good luck
In both cases,

(as a consequence of the interesecting secant-tangent theorem)
So we have
10.





(omit the negative solution because that would make at least one of AB or AD have negative length)
11.




(again, omit the solutions that would give a negative length for either AB or AD)
2x+50 + 3x= 90 degrees
5x +50 = 90
5x =40
x=8
Angle1= 2(8) +50= 66
Angle2= 3(8)=24
66+24+90= 180
