Answer:
2d = 58 (If you are just finding d then d = 29)
Step-by-step explanation:
69 + 53 = 122
180 - 122 = 58
29
The total degree of a triangle is 180 so
(69 + 53) + 2d= 180
122 + 2d= 180
2d= 180-122
2d= 58
Divide both side by 2
which 29
BUT
i dont really understand if the 2 was the multiple or it just "2d"
in that case "2d" would be 58.
P(a or b) = P(a) + P(b) - P(a and b)
0.88 = 0.70 + 0.60 - P(a and b)
P(a and b) = 1.30 - 0.88 = 0.42.
So the events a and b are not mutually exclusive.
u-y = xk
(u-y)÷k = x
This is the answer.
