Answer:
28
Step-by-step explanation:
you could wright the equation like 15/100=4.20/x
All I did is 100 divided by 15, which is 6.6666667, and then multiply that number by 4.20.
I hope this helped you!
Answer:
1/2 or 0.5
Step-by-step explanation:

The trigonometric function gives the ratio of different sides of a right-angle triangle. The given problems can be solved as given below.
<h3>What are Trigonometric functions?</h3>
The trigonometric function gives the ratio of different sides of a right-angle triangle.

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
1st.) x = 5 /Sin(30°)
x = 10
!) sin(45°) = 4/x
x = 4/sin(45°)
x = 4√2
I) Cos(45°) = √3 / x
x = √3 / Cos(45°)
x = √6
E) Tan(60°) = 3√3 / x
x = 3√3 / 3
W) For isosceles right-triangle, the angle made by the legs and the hypotenuse is always 45°.
x = 45°
N) x² + x² = (7√2)²
x = 7
V) Tan(60°) = 7 / x
x = 7√3/3
K) x² + x² = (9)²
x = 9/√2
Y) Sin(60°) = 7√3/x
x = 14
M) Sin(30°) = x/11
x = 11/2
T) Sin(45°) = x/√10
x = √5
A) x + 2x + 90° = 180°
x = 30°
O) Sin(45°) = √2 / x
x = 2
R) Tan(30°) = x / 4
x = 4/√3 = 4√3 / 3
S) Sin(60°) = x / (10/3)
x = 5√3 / 3

Your goal here is to determine the value of x.
Use the principle of similar triangles:
x is to 12 as 6 is to 8:
x 6
--- = ----
12 8
Therefore, 8x = 72, and x = 9 (answer)
Y = 1/4 x^3 + 2
1/4 x^3 = y - 2
x^3 = 4(y - 2)
x = cube root (4y - 8)
inverse y = cube root (4x - 8)
Its D.
