Question

Help on both problems pls

Answer 1

DE = √21

x = 10

Explanation:

4)

AC is bisected by BX

AC/2 = 8/2 = 4 = AB

BX² + AB² = AX²

3² + 4² = AX²

AX = 5 = radius of the circle

DE² = DX² - EX²

DE² = 5² - 2² = 25 - 4 = 21

DE = √21

6)

x² = (11-5)² + 8² = 36 + 64 = 100

x = √100 = 10

x = 10
