Consider a triangle abc like the one below. suppose that a = 27°, c = 78°, and b = 66. (the figure is not drawn to scale.) solve
the triangle.
round your answers to the nearest tenth.
if there is more than one solution, use the button labeled "or".

We don't get to see the figure but we don't need it.

The remaining angle B is

B = 180 - 27 - 78 = 75°

The Law of Sines gives the remaining sides

B=75°, a=31.0, c=66.8

No need for "or" on this one.  That happens when we know the sine of an angle so there are two possibilities for the angle, an acute one and an obtuse one that's supplementary.

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.
