Can someone me on this pls identify the property that is being applied at each step to simplify the expression

We are given

First expression:

We used property

power rule-II:

Product to power distribute  to each base

Second expression:

we used property

associative property of multiplication:

Third expression:

we used property

Product Rule:

Same base add exponents

Fourth expression:

we used property

Zero Exponent :

Anything to the zero power  (except 0) is one

Fifth expression:

we used property

Multiplicative identity:

Sixth expression:

We used simplification

b mark me branliest thx

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
