Answer:

X = 12

Step-by-step explanation:

If the angle depicted on top is the angle for the inside angle in the triangle, we can find x easily. a line is 180 degrees so we can do 180-151 for the right inside angle. that's 29. we can do 5x+3+9x-20+29 = 180. 14x+12=180. 14x = 180-12. 14x = 168. 168/14 = 12

romanna [79]

Given :

A man 1.30 m tall is on a top of a building. He observed a car on the road at an angle of 60 degrees if the building is 30 m high.

To Find :

How far is the car from the building.

Solution :

Let, distance between car and the building is x m.

So,

tan \ \theta = \dfrac{height\ of\ building + height\ of\  man}{distance \ between \ car \  and \ building}\\\\tan \ 60^o = \dfrac{30+1.3}{x}\\\\x = \dfrac{31.3}{1.73}\ m\\\\x = 18.09\ m

Hence, this is the required solution.

Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph.
Galina-37 [17]

I do believe it is -1 1/2 because I chose two points on the graph (0, 300) and (150, 200). To find slope you need to plug it into an equation, which in this case looks like, (150-0)/(200-300) which then goes to 150/-100, which then simplifies to 15/-10, and then it converts to -1 1/2.
