Solve for x. round to the nearest tenth

x ≈ 11.1

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos42° = = ( multiply both sides by 15 )

15 × cos42° = x, then

x ≈ 11.1 ( to the nearest tenth )

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,
