A man walks 4km from point x due east of point Y. The bearing of a flag point x and y are due N80°W and N40°E respectively. Find
In-s [12.5K]

The distance of the flag pole from point Y is 0.8 km and it is placed at an bearing of N40°E

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Sine rule shows the relationship between the sides and angles of a triangle.

The triangle formed has angles A = 10°, B = 50°, C = 120°, c = 4 km, a = distance from point y.

Hence:

a / sinA = c / sinC

a / sin(10) = 4 / sin(120)

a = 0.8 km

The distance of the flag pole from point Y is 0.8 km and it is placed at an bearing of N40°E

4x-2y&lt;-2<br><br>a) (2,8) b) (0,1) c) (3,7) d) (5,8)​
amm1812

Answer:

a) (2, 8)  

Step-by-step explanation:

The easiest way is to insert the coordinates into the inequality.

a) (2, 8)

\begin{array}{rcl}4(2) - 2(8) & < & -2\\8 - 16 & < & -2\\-8 &< & -2\\\end{array}\\\textbf{TRUE}

b) (0, 1)

\begin{array}{rcl}4(0) - 2(1) & < & -2\\0 - 2 & < & -2\\-2 &< & -2\\\end{array}\\\text{False}

c) (3, 7)

\begin{array}{rcl}4(3) - 2(7) & < & -2\\12 - 14 & < & -2\\-2 &< & -2\\\end{array}\\\text{False}

d) (5, 8)

\begin{array}{rcl}4(5) - 2(8) & < & -2\\20 - 16 & < & -2\\4 &< & -2\\\end{array}\\\text{False}

You could also plot the inequality and test the points. You would get a graph like the one below. Point (2, 8) is the only one that satisfies the inequality. Points (0, 1) and (3, 7) do not satisfy the inequality because they are on a dashed line.

Arthur is treating his friends to a meal at Chez rich. The meals add up to $136.45. If he tips the waiter 15% what is the amount
Ulleksa [173]
Basically you need to find what 15% of 136.45 is. You do this by changing the percent to a decimal, so 15% would be .15. Following this, you would multiply 136.45*.15. This will give your answer.

Draw triangle GMT<br><br> PLS CREATE DRAWING!! refer to attachment
jekas [21]

The angle between sides GM and MT is ∠M.

The 2 sides that include ∠T are MT and GT.

The angle between sides GT and MG is ∠G.

There's not much to say about this, but I can answer questions if you have any.
