CD = x
BC = y
AB = 85
BD = BC+CD = y+x

tan(angle) = opposite/adjacent
tan(28) = BC/AB
tan(28) = y/85
85*tan(28) = y
y = 85*tan(28)
y = 45.1953016912257

tan(angle) = opposite/adjacent
tan(31) = BD/AB
tan(31) = (y+x)/85
tan(31) = (45.1953016912257+x)/85
85*tan(31) = 45.1953016912257+x
51.0731526173427 = 45.1953016912257+x
51.0731526173427-45.1953016912257 = 45.1953016912257+x-45.1953016912257
5.877850926117 = x
x = 5.877850926117

So CD is roughly 5.877850926117 meters

Compute the number of vinyl tiles, measuring 25 cm each side, needed to tile a kitchen measuring 102 ft. by 18 ft. Try not to ro
nadya68 [22]

Answer:   2730 tiles (Approx)    

Step-by-step explanation:

Since, The side length of each side = 25

According to the question the shape of the tile is square.

Thus, the area of one tile = 25 × 25 = 625 cm^2

Also, we need to tile a kitchen measuring 102 ft. by 18 ft

Thus, the area of the room in which we have to tile =  102 × 18 = 1836 feet^2 = 1836×30.48 × 30.48 = 1705699.8144 cm^2

Thus, the total number of the tiles = the area of the room in which we have to tile / the area of one tile = \frac{1705699.8144}{625} = 2729.11970304

Since, we must take 2730 tiles to tile the kitchen.

Answer:

  x = 6

Step-by-step explanation:

You can actually work out the answer yourself.

The two angles shown have the total measure 168°, so the unmarked one is ...

  168° -100° = 68°

That is ∠WXZ, so we know ...

  68° = (5x +38)°

  30 = 5x . . . . . . . . . . divide by °, subtract 38

  6 = x . . . . . . . . . . . . .divide by 5
