Answer:

78°

Step-by-step explanation:

angle CAW=180-168

angle CAW=12

angle DWB=12 vertically opposite to angle CAW

Sum of angles at a point=360

168+12+12+90+w=360

282+w=360

Collect like terms

w=360-282

w=78

Answer:

A reasonable estimate  for the solution is the point (1.1,-1.9)

Step-by-step explanation:

we have

y=-\frac{3}{4}x-1 -----> equation A

y=2x-4 ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the interection point both graphs

using a graphing tool

The solution is the point (1.091,-1.818)

see the attached figure

therefore

A reasonable estimate  for the solution is the point (1.1,-1.9)

A length of string that is 240 cm long is cut into three pieces the second piece is 25% longer than the first piece the third pi
Tresset [83]
Hey there,
Let's say that the first piece is x cm
1st = x
2nd = x + 25%
3rd = x - 25%
100% = 240 cm
1% = 240 / 100
      = 2.4cm
x + x + 25 + x - 25 = 100
3x + 25 - 25 = 100
3x = 100 - 25 + 25
3x = 100
3x = 240 cm
x = 240 / 3
   = 80 cm
1st piece = 80 cm
2nd piece = 80 + (25% x 80)
                = 80 + 20
                = 100cm
3rd piece = 80 cm - (25% x 80)
                = 80 cm - 20
                = 60cm

Hope this helps :))
