Answer:
x=2.4
Step-by-step explanation
Lets take the info already given. 20 is on the larger triangle and 8 is on the smaller. So the side that matches with X is 6. The relationship between 20 and 8 is 2.5. How? 20/8=2.5. then you divide 6 by 2.5. That equals 2.4. So x=2.4. Hope that helps !

Step-by-step explanation:
The arc of a circle is calculated as
arc = circumference of circle × fraction of circle
Here arc = 22 , then
2πr × 
= 22
2πr × 
= 22 ( multiply both sides by 9 to clear the fraction )
2πr = 198 ( divide both sides by 2π )
r = 
≈ 31.5 cm
Answer:
root 11
Step-by-step explanation:
AB = 6
BC = 5
AC = LET X
SO,
H²= P²+ B²
6²=X²+5²
36-25=X²
X= ROOT 11
