Answer:
∠ EFH = 112°
Step-by-step explanation:
∠ ACD and ∠ EFH are Alternate exterior angles and are congruent, thus
11x - 20 = 9x + 4 ( subtract 9x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Thus
∠ EFH = 11x - 20 = 11(12) - 20 = 132 - 20 = 112°
Step-by-step explanation:
Substitute r = 3 and h = 5 into the formula. Volume V=13⋅π⋅9⋅5=15πcm3=47.1cm3.
The first number would be 3×5=15.
Another number could have different values. it could be
4=2×2
12=2×2×3
20=2×2×5
60=2×2×3×5
Answer:
x = 2
Step-by-step explanation:
x + 1 + 4 = 2x + 3
x + 5 = 2x +3
x + 2 = 2x
2 = x
x = 2
