Answer:
An arithmetic sequence is made up of terms. In Mathematics, a term means each of the quantities in a ratio, series, or mathematical expression. For example, a series of numbers regarding an arithmetic sequence would be 9, 6, 3, 0, -3, -6, -9. Therefore, an arithmetic sequence is made up of terms.
Answer:
x = 21
Step-by-step explanation:
2x and 42 are alternate angles and are congruent, so
2x = 42 ( divide both sides by 2 )
x = 21
Answer:
x = 3
Step-by-step explanation:
Recall: Opposite angles in an inscribed quadrilateral are supplementary.
Thus,
m<R = 180 - m<P
m<R = 180 - 110
m<R = 70°
Recall: measure of inscribed angle = half of the intercepted arc
Thus:
m<R = ½(arc KPQ)
70 = ½(50 + 30x)
Multiply both sides by 2
2*70 = 50 + 30x
140 = 50 + 30x
140 - 50 = 50 + 30x - 50
90 = 30x
90/30 = 30x/30
3 = x
x = 3
