Answer: The triangle mentioned here is an acute angled triangle.
Step-by-step explanation: x+x+10+2x-6=180°(angle sum prop. of triangles)
= 4x+4=180°
= 4x=174°
= x=44°
therefore, x=<u>44°</u>
,x+10=44+10=<u>54°</u>
,2x-6=2(44)-6=<u>82°</u>
Answer:
s / ( 2 pi * h) = r
Step-by-step explanation:
s = 2 * pi * r * h
Divide each side by 2 * pi * h
s / 2 pi h= 2 * pi * r * h/ ( 2 pi h)
s / ( 2 pi * h) = r
