Answer:

<h2>             39°</h2>

Step-by-step explanation:

A radius to the tangent point always forms a right angle with the tangent:

m∠XWY = 90°

So:

  90° + 58° + x - 7° = 180°

    141° + x = 180°

        x = 39°

The area of a trapezoid is
horrorfan [7]

Answer:

<h2>The answer is 15cm</h2>

Step-by-step explanation:

Let b be the length of the second parallel side

Area of a trapezium is given by

A =  \frac{1}{2} (a + b)h

where

h is the height

a and b are the parallel sides

From the question

Area = 230 cm²

height = 20cm

one of parallel side / a = 8 cm

Substitute the values into the above formula and solve for b

That's

230 =  \frac{1}{2} ( 8 + b) 20

Reduce the fraction with 2

That's

230 = (8 + b) \times 10

Expand the terms

That's

230 = 80 + 10b

10b = 230 - 80 \\ 10b = 150

Divide both sides by 10

We have the final answer as

<h3>b = 15cm</h3>

Hope this helps you
