I'm working on a webpage concerning the calculation of all three altitudes (heights) of an obtuse triangle. I have made a graphic (attached) which I think is appropriate for just about ANY obtuse triangle.
I'm assuming that the heights are labeled according to which vertex AND side the height is connected to. For example, the height labeled h (sub b) connects Vertex B to side b.
Is my drawing accurate, labeled correctly, etc.
I'm very sure I can calculate the lengths of the altitudes but I will also attach those equations too.

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
