Answer:

  x° ≈ 50.0°

Step-by-step explanation:

The sides adjacent and opposite the angle are given. The appropriate trig relation is ...

  Tan = Opposite/Adjacent

  tan(x°) = 50/42

The inverse function is used to find the angle whose tangent is a particular value:

  x° = arctan(50/42) ≈ 49.9697°

  x° ≈ 50.0°

Answer:

6 in^2.

Step-by-step explanation:

The area of 2 similar figures are in the ratio of the squares of corresponding sides. So we have the equation:

3^2 / 6^2 = x / 24

9/36 = x /24

1 / 4 = x / 24

x =  24/4 = 6 in^2 (answer).

If the area of the given trapezoid is 1,188m^2, find the value of x.
VMariaS [17]

Answer: x = 52 m

Step-by-step explanation:

     The formula we will use, which solves for the area of a trapezoid, is a=\frac{a+b}{2} h where a is a base, b is a base, and h is the height.

    We will input the known values, then solve for <em>x</em>.

         \displaystyle a=\frac{a+b}{2} h

         \displaystyle 1,188\;\text{m}^2=\frac{36\;\text{m}\;+x}{2}*27\;\text{m}

         \displaystyle 1,188\;\text{m}^2=(18\;\text{m}+\frac{x}{2})*27\;\text{m}

         \displaystyle 1,188\;\text{m}^2=486\;\text{m}+\frac{27x}{2}

         \displaystyle 702\;\text{m}^2=\frac{27x}{2}

         \displaystyle 1,404\;\text{m}^2=27x

         \displaystyle x=52\;\text{m}
