Answer:
x^2 – 4 = 0
Step-by-step explanation:
When x = - 2,
x^2 - 4 = 0
( - 2 )^2 - 4 = 0
4 - 4 = 0
When x = 2,
x^2 - 4 = 0
2^2 - 4 = 0
4 - 4 = 0
Answer:
x = 4°
Step-by-step explanation:
all angles in a triangle sum up to 180°
6x + 38° + 5x + 8° + 90° = 180 °
11x +136° = 180°
11x = 44°
x = 4°
Distance from the boat to the town:
d² = 2.2² + 16.8²
d² = 4.84 + 282.24
d² = 287.08
d = √287.08
d = 16.9434 ≈ 16.9 km
