Answer:
5x<12
Step-by-step explanation:
Five times x is equally 5x fewer than is equally < # 5x<12
56=2(pi)(r)
r=8.9127
pi(8.9127)^2=249.56cm^2
≈245cm^2 (3s.f.)
Let's use tenths.
1/10 = 0.10
5/10 = 0.50

Answer:
45.367 cm
Step-by-step explanation:
Approximating to a more number of decimal places gives a better estimation of the exact value.
For 45.367 cm, we approximated to three decimal places or five significant figures.
For 43.43 cm, the approximation is done to four decimal places.
Therefore the measurement 45.367cm is more precise because it has a relatively smaller error.
1) angle 2 = angle 4
115 = 3x + 16
115 - 16 = 3x
99 = 3x
x = 33
2) angle 2 + angle 5 = 180 degrees
115 + angle 5 = 180
angle 5 = 180 - 115
angle 5 = 65 degrees
3) Angle 1 is equal to 120 degrees
