Answer:
Therefore the value of x is 25.8 unit.
Step-by-step explanation:
Given:
AB =Tangent = y
BE = secant segment = 5
BC = secant segment = 7
EF = x
CD = 15
To Find :
x = ?
Solution:
Tangent-secant theorem:
"When a tangent and a secant are drawn from one single external point to a circle, square of the length of tangent segment must be equal to the product of lengths of whole secant segment and the exterior portion of secant segment."
Here we have
AB =Tangent
BC = secant segment = 7
BD = exterior portion of secant segment = BC +CD =7 + 15 = 22
So on applying Tangent-secant theorem we get
Substituting we get
Now again applying Tangent-secant theorem for different secant we get
Substituting we get
Therefore the value of x is 25.8 unit.
Answer:
C & B
Step-by-step explanation:
Answer: C - 15.81
Step-by-step explanation:
pythagorean theorum: a^2 + b^2 = c^2
13^2 + 9^2 = c^2
169 + 81 = c^2
c^2 = 250
root both sides
c = 15.81
Answer:
For the first one, just make sure the sides add up correctly and include the sides it gives. The prism will be 9x1x8 = 82 inches cubed.
