Answer:
x = 70°
Step-by-step explanation:
Itz given that AB & CD are perpendicular to each other and intersect at E . So , angle(AED) = 90°
But here the value of angle(AED) = 90°
So,
x + 20 = 90°
=> x = 90° - 20°
= 70°
The surface area of the cylindrical ring is given by
πdh
where d is the diameter and h is the height:
π•6.3•48 = 950.02
The answer is C. 950.02 in^2
Answer:
I thank its b not sure sorry if its wrong
Answer:
Step-by-step explanation:
you could do (960/100)*80=768
72, 96, 84, 12
72 + (7x+24) = 180
7x + 96 = 180
7x = 84
x = 12
