The scale factor from the first map to the second map can be determined by:
scale factor = (length of trail in first map) / (length of trail in second map)
8 cm / 6 cm = 1.33
The landmark on the first map is a triangle with side lengths of 3mm, 4mm, and 5mm.
3mm = 3 * 1.33 mm = 3.99mm
4mm = 4 * 1.33 mm = 5.32mm
5mm = 5 * 1.33 mm = 6.65mm

Answer:
27
Step-by-step explanation:
I'll solve 21, and you then should be able to solve the rest on your own!
Since ADC is 135, that means that that whole angle is 135 degrees. In addition, since angles ADB and BDC add up to ADC, we get ADB+BDC=ADC=135=11x+9+7x=18x+9. Subtracting 9 from both sides, we get 126=18x. Dividing both sides by 18, we get x=7. Plugging that into 11x+9=BDC, we get 11*7+9=77+9=86
