Answer:
24.187
Step-by-step explanation:
To find your missing angle:
180-126 = 54
so 9x must equal 54
54= 9x
6 = x
If 5 biscuits cost 40p
1 biscuit would cost (40p divided by 5) 8p
8p multiplied by 3 (to get 3 biscuits) would cost 24p
3 biscuits cost 24p
Answer:
50
Step-by-step explanation:
Because of supplementary angles that line has to equal to 180
180-75 = 105
so 105 = (2x + 5)
you can subtract 5 from each side and get
100 = (2x)
then divide each side by 2 and you get
x = 50
you can check it by doing (2 x 50 + 5)
2 x 50 = 100 + 5 = 105 + 75 = 180
