Hi my name is Argie, I had to do a scribepost and I chose question 4 on page 110.
4) Find the height of the pole where the guy wire is attached, round to the nearest tenth of a meter.
c² - a² = b²
10² - 2² = b²
10x10 - 2x2 = b²
100 - 4 = b²
96 = b²
√96 = √b²
9.7m = b
The height of the pole would be 9.7m.
PLEASE COMMENT, THANKS FOR READING.
