It would be C because bisectors split the angle in half
Answer:
let the numbers be
X , y and z
X+ y + z = 20
first number is 4 times the sum of other 2
X = 4(y+ z)
second is 7 times third
y = 7z
now substituting back
X= 4 (7z + z)
X= 32z
32z + 7z + z = 20
40z = 20
z = 1/2
y = 1/2 * 7 = 7/2
X = 1/2 * 32 = 32/2
1/2 * 7/2 * 16 = 28
28 is the answer!
Answer:
option is B because to find the slope u would have to do Y1-Y2/X2-X1
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.
