A=100°
as 180-140= 40 , 40 x 2 = 80 & 180-80 = 100° = a
no because it is not a right angled triangle.
this means angle A is not 90° so AB cant be a tangent.

Step-by-step explanation:1
Convert 1121\frac{1}{2}121 to improper fraction. Use this rule: abc=ac+bca \frac{b}{c}=\frac{ac+b}{c}acb=cac+b.
34+3.3−1×2+12\frac{3}{4}+3.3-\frac{1\times 2+1}{2}43+3.3−21×2+1
2
Simplify 1×21\times 21×2 to 222.
34+3.3−2+12\frac{3}{4}+3.3-\frac{2+1}{2}43+3.3−22+1
3
Simplify 2+12+12+1 to 333.
34+3.3−32\frac{3}{4}+3.3-\frac{3}{2}43+3.3−23

20 cookies because y = 8 + 6(x)
X = 2 since half of the cookies left was 6
6(2) = 12 and 12+8 = 20
So in total she baked 20cookies
