Answer:
Your answer is 7.0
Step-by-step explanation:
If the circles are congruent and RQ measures 35.6, then so does CB. That means that half of it (the radius XD which measures 26 cuts the length of CB in half) is 17.8. If the base of that right triangle is 17.8 and the hypotenuse is 26, then Pythagorean's Theorem tells us that the height of the triangle is 18.95151709. Subtract that from the radius length of 26 and you'll have the length of DE
