Answer:
m∠1 = 50°, m∠2 = 90°, m∠3 = 40°, and m∠4 = 50°
Step-by-step explanation:
Angles on straight line are equal;


Vertical angles are equal,

Complementary angles add up to 90°.

Angles on straight line adds up to 180°


Answer:
no solution
Step-by-step explanation:
Given
- 3 | 6n - 2 | + 5 = 8 ( subtract 5 from both sides )
- 3 | 6n - 2 | = 3 ( divide both sides by - 3 )
| 6n - 2 | = - 1
The absolute value always returns a positive value and so
| 6n - 2 | ≠ - 1
Hence there is no solution to the equation
Answer:
The point C is 12.68 km away from the point A on a bearing of S23.23°W.
Step-by-step explanation:
Given that AB is 50 km and BC is 40 km as shown in the figure.
From the figure, the length of x-component of AC = |AB sin 80° - BC cos 20°|
=|50 sin 80° - 40 cos 20°|=11.65 km
The length of y-component of AC = |AB cos 80° - BC sin 20°|
=|50 cos 80° - 40 sin 20°|= 5 km
tan
= 5/11.65
=23.23°
AC=
km
Hence, the point C is 12.68 km away from the point A on a bearing of S23.23°W.
