Angles in a traingle always add up to 180°. in an isosceles triangle, 2 of the angles are the same, so if one angle is 100°, the other 2 must be 180-100=80/2=40
the other 2 angles would be 40° and 40°
Answer:
the third one
Step-by-step explanation:
You flip 3 coins 20 times and record the number of heads. The results are listed below. 2, 1, 0, 2, 2, 0, 2, 2, 3, 2, 1, 2, 1, 2

Assuming a is 0, b is 1, c is 2, d is 3
a= 2, b= 7, c= 9, d= 2
9.5
If you add 12.4 plus 12.4 you get 24.8 then you do 43.8 minus 24.8 and you get 19 and 19 divided by 2 is 9.5
9.5+9.5+12.4+12.4=43.8
18= +5+x
x=3
If you do 3•5, you get 15.
Then do 3+15, you get 18.
