The hypotenuse is 20 ft
Step-by-step explanation:
- Step 1: This is a right triangle, so the trigonometric ratio cosine can be used to find the length of the hypotenuse. Given side opposite to ∠B, AC = 18 ft and ∠A = 40°,
cos 40° = adjacent side/hypotenuse = AC/AB = 18/AB
⇒ AB = 18/cos 40° = 18/0.76 = 23.5 ft ≈ 20 ft
Answer:
n = - 19
Step-by-step explanation:
8n - 9n - 2 = 17 , that is
- n - 2 = 17 ( add 2 to both sides )
- n = 19 ( multiply both sides by - 1 )
n = - 19
