Answer:
4/9
Step-by-step explanation:
There are 9 positive integers less than 10: {1, 2, 3, 4, 5, 6, 7, 8, 9}.
The 4 primes less than 10 are ... {2, 3, 5, 7}.
The probability Daria selected a prime is 4/9.

SSS similarity states that all 3 sides must be proportional for the triangles to be similar
Here is your answer
50
Using cosine law,
d^2 = 65^2 + 35^2 - 2(65)(35)cos140
= 8935.5022
d = sqrt(8935.5022)
= 94.5 m
Angle = inverseCos(35sin40 / 94.5) = 76.23 degrees South of East
2x4 8.2
y=30
y-8=22
Add 8 on both sides
