Find m can someone me with number 10

m(PRS) = 98°

m(PRQ) = 3x-8°

m(QRS) = 2x+6°

Also,

m(PRS) = m(PRQ)+m(QRS)

98 = 3x-8 + 2x+6

98 = 5x-2

98+2 = 5x

5x = 100

x = 20°

So, now we put x = 20° in m(QRS) given

m(QRS) = 2x-6 = 2(20)-6 = 40-6 = 32°

Therefore, m(QRS) = 32°

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

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.
