Answer:
y = 14°
Step-by-step explanation:
50° = 2x° (isosceles triangle theorem)
50° + 2x° + (5y + 10)° = 180° (The sum of the three angles of any triangle is equal to 180 degrees.)
Answer:
15 = X . hope this helped
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.
