It belongs to Q, The st of RATIONAL NUMBERS. It's written in terms of set:
1/4 ∈ Q={1/4, I 1∈Z, q∈Z, with q≠0}
Answer:
Number 3 is the correct awnser
Your numbers are confusing
3n+2n+4=9n+12
5n+4=9n+12
4-12=9n-5n
-8=4n
Divide both sides by 4
n=-2
Answer:
x = 58°
Step-by-step explanation:
Length of tangents drawn to a circle from a point outside the circle, are equal in measure.
By using this property,
Two tangents PQ and PR will be equal.
And angles opposite to these sides will be equal.
Therefore, ∠PQR ≅ ∠PRQ
By triangle sum theorem,
m∠PQR + m∠PRQ + m∠QPR = 180°
x° + x° + 64° = 180°
2x = 180 - 64
2x = 116
x = 58°
180degree should be the value of B
