Find the value of x. Round to the nearest tenth.

10.8

Step-by-step explanation:

We need to use the cosine:

cos(26deg) * 12 ~= 0.89879404629 * 12 ~= 10.7855285556 ~= 10.8

$12. that is my answer.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
