1 in 10 is the probability of two people picking the same number.
Answer:
this angle is a right angle(90°)
and one of the 2 angles is 30
3x+30=90
3x=90-30
3x=60
x=20
==> B
It’s going to be the area of the triangle on the side times the length, so 0.5 x 36 x 15 x 48 = 12960
(10 + 9) x (3 - 1) x 2 = +75
19 x 2 x 2
76
76 > 75
