Is there a pic showing ABC? it will be evil if BC is the hypotenuse itself lol
assuming dats not the case here,
tan B = CA/BC
so 0.58333 = CA/12
CA = <span>69.9996
the hypotenuse, AB = sqrt (12^2 + </span><span>69.9996^2)
= 71.02
= 71.0

Answer:
145
Step-by-step explanation:
In this geometry, the central angle (x°) and the external angle (35°) are supplementary.
x° = 180° -35°
x = 145
Hope this helps!

Answer:
lateral surface area of the cone =49π
Step-by-step explanation:
y= x/4
dx/dy = 4
Given x range as from 0 ≤ x ≤ 7 ⇒ x ranges between (a,b)
a= x/4 = 0/4 = 0
b = x/4= 7/4
lateral surface area of the cone
=32π * 49/(16 *2)
=49π
