Step-by-step explanation:
Measured height = 5.61 feet
Original height = 6 feet
Error in measurement = Original height - Measured height
Error in measurement = 6 - 5.61
Error in measurement = 0.39 feet
Percentage of error in David's measurement is 6.5 %
Answer:
3
9/3
46 is greater than -79
True
25
Let us assume that m<1 nad m<2 are supplementary. Since the sum of supplementary angles is 180degrees, hence;
<1 + <2= 180
123+2x+7 = 180
130+2x = 180
2x = 180 - 130
2x = 50
x = 50/2
x = 25
Hence the value of x is 25
