Answer:
Addition property of equality (1st option)

Step-by-step explanation:
x - 7 = 5
By adding 7 to both the sides,
x - 7 + 7 = 5 + 7
And cancelling 7 in the LHS & adding 5 to 7 in the RHS,
x = 12

Mountain officials want to know the length of a new ski lift from A to C , as shown in the figure below. They measure angle DAC
Ede4ka [16]
We assume that the hill is represented by points ACD  and the ski lift is represented by points BCD. From the description above, points CDB would have an angle of 90 degrees. Then, we would have:

sin (32) = CD / 960
CD = 508.72

tan 32 = 508.72 / AD
AD = 814.13

Therefore, the distance would be 814.13 - 508.72 = 305.4 ft.
