Answer:

x°= 55°

Step-by-step explanation:

First, find the degrees of the larger triangle.

Since every triangle equals 180° degrees, make an equation.

60°+90°+a°= 180°

Now, add the degrees together.

120°+a°= 180°

Then subtract from both sides.

120°+a°= 180°

-120 °      -120°

a°= 60°

Now that you know the sum of all the angles, subtract 25° from 60°(which is the measure of a).

60°-25°= 35°

Now that we have the measurement of the angle from the smaller triangle inside the larger one, make an equation.

35°+90°+x°= 180°

Then, add the degrees.

125°+x°= 180°

Subtract from both sides of the equation to get the answer for the variable.

125°+x°= 180°

-125°       -125°

x°= 55°

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h. A=h ( a+b ) 2 Solve for b.
Lelu [443]
I believe the right equation for determining the area of a trapezoid is as below,
     A = h(a + b)/2

To determine the expression for b which is the length of one of its bases, we multiply the equation by 2.
    
    2A = h(a + b)

Then, divide both sides of the equation by h,

    2A/h = a + b

Then, subtract a from both sides of the equation,
    2A/h - a = b

Lastly, interchange the sides of the equation to reveal the answer.
<em>     </em>
<em>   b = 2A/h - a </em>
