Answer:
The answer would be 13.3.
Step-by-step explanation:
Use the Pythagorean theorem to find the other distances in the 5, 3, x triangle and the 7, 3, y triangle and add those two answers together plus 3 to get your answer.
Answer:
13,3km is nearest 10th ( which is the same for 1dp 13.3km) (13.32km 2dp)
Step-by-step explanation:
Horizontal distance is need for Pythagoras
Reading measurements given left to right we find;
c-b = a
c-b =x
c-a = b
Finding x
5sq - 3sq = xsq
√25 - √9 = √16 = √x
√16 = √x = 4
x = 4
Finding y
7sq - 3sq=ysq
√49-√9=√40 = √y
√40 = √y = 6.32
y = 6.32
Therefore x+y+3 = horizontal distance
4 + 6.32 +3 = 13.32km nearest 10th km is 13.3 km
