Answer:
x = 5
Step-by-step explanation:
GE is the angle bisector of quadrilateral DEFG,
Thus, by angle bisector property:
9x°= (5x + 20)°
9x = 5x + 20
9x - 5x = 20
4x = 20
x = 20/4
x = 5
Answer: 26 Minutes
Step-by-step explanation:
3 mi * 1.609 km/1 mi = 4.82 km
4.82 km/ 18 minutes = 7 km/ x minutes
4.82x=18*7
x=126/4.82
x=26.14 ~ 26 Minutes
Surface area = 2(12*12+15*12+15*12) = 1008
1008 * 4 = 4032
These are the answers for the first 2 questions

<em>1.</em> 16.956 m
<em><u> formula:</u></em> C = 2πr
C = 2(3.14)(2.7)
C = 6.28(2.7)
C = 16.956
<em>4.</em> 15.7 ft.²
<u><em>formula:</em></u> C = πd
C = 3.14(5)
C = 15.7
