Answer:
an = 10 + (-2)(n-1)
Step-by-step explanation:
We are given from the sequence first term, a1 = 10
common difference, d = a2 - a1
Where; a2 = second term = 8
d = 8 - 10 = -2
From the formula, an = a1 + d(n - 1),
We substitute the value of a1 and d
therefore, an = 10 + (-2)(n - 1)
Answer:
<em>x = 17°, m∠ A = 114°</em>
Step-by-step explanation:
We can tell that these pair of angles are corresponding, provided;
Line 1 ║ Line 2, AB ∩ Line 1 and Line 2 ⇒ corresponding ∠s ≅,
m∠ A = m∠ B ⇒ Substitute values of A and B,
6x + 12 = 3x + 63 ⇒ Subtract 3x on either side,
3x + 12 = 63 ⇒ Subtract 12 on either side of equation,
3x = 51 ⇒ Divide either side by 3,
<em>x = 17 </em>⇒ Substitute value of x to solve for m∠ A,
m∠ A = 6 * ( 17 ) + 12,
m∠ A = 102 + 12,
<em>m∠ A = 114</em>
<em>Solution; x = 17°, m∠ A = 114°</em>
