Answer 1

Answer:

$x=25$

Step-by-step explanation:

If the figures are similar, then the angles are the same. So that means that angle H is equal to angle D (you can count he little arcs in the angle to find it's matching partner). Since this is true:

$4x=100$

Which is the same as $D=H$. Solve for x by dividing both sides by 4:

$\frac{4x}{4} =\frac{100}{4} \\\\x=25$

Finito.
