x = 4/cos72
x = 12.9
Answer:
The length of x=3/1
Step-by-step explanation:
Given the right triangle
Ф = 30
We know that
sin Ф = opposite/hypotenuse
The opposite of angle 30° = x
The hypotenuse is = 6
so
sin 30 = opposite/hypotenuse
1/2 = x/6 ∵ sin 30 = 1/2
1/2 × 6 = x
6/2 = x
3/1 = x
Therefore, the length of x=3/1
Answer:
30/29
Step-by-step explanation:
5 feet is 5*12 = 60 inches
Fraction is (60 in)/(58 in)
(60 in)/(58 in) = 30/29
X+y=27
x=2y
2y+y=27
y=9
x=27-y
x=27-9=18
