Answer:
Additive Identity Property
Step-by-step explanation:
Additive Identity Property means that when you add 0 the answer will always equal the other number.
Other examples of this property:
3+0=3
0+7=7
9+0=9
1. (c) 125/12
2. (a) 16

Cos( 30 ) = 19√3 / x
√3 / 2 = 19√3 / x
Simplify √3 from both sides
1 / 2 = 19 / x
Multiply both sides by x
1 /2 × x = 19 / x × x
x / 2 = 19
Multiply both sides by 2
x / 2 × 2 = 19 × 2
x = 38
_____________________________
Sin( 30 ) = y / x
1 / 2 = y / 38
Multiply both sides by 38
38 × 1 / 2 = 38 × y / 38
38 / 2 = y
19 = y
y = 19
