Answer:
225 minutes
Step-by-step explanation:
45 min = 20% = 20/100
20 x 5 = 100
45 x 5 = 225
Answer:
x = 76.80°
4x - 142 = 165.18°
x/5 = 15.36°
5x/9 + 60 = 102.66°
Step-by-step explanation:
Total angle in a quadrilateral is 360
x + 4x - 142 + x/5 + (5/9)x + 60 = 360
259x/45 + - 82 = 360
259x/45 = 442
x = 76.7953668
x = 76.80°
4x - 142 = 165.18°
x/5 = 15.36°
5x/9 + 60 = 102.66°
Answer:
C. AB = 5.8 cm
Step-by-step explanation:
In trapezoid ABCD, EF is the Midsegment.
.:. EF = {(AB+CD)
.:: 9.2 = {(AB + 12.6)
:: 9.2 x 2 = AB + 12.6
.. 18.4 = AB + 12.6
.. 18.4-12.6 = AB
:: AB = 5.8 cm
