6.66666666667% you divide 120 by 18 that = 6.66666666667 and add a %
Supplementary angles sum up to 180°. Take the missing angle as 'x'.
148 + x = 180
x = 180 - 148
x = 32°
=》 Angle ABD = 32°

Find an explicit formula for the arithmetic sequence -45,-30,-15,0,...−45,−30,−15,0,...minus, 45, comma, minus, 30, comma, minus
juin [17]
Answer:
= 15n - 60
Step-by-step explanation:
The n th term ( explicit formula ) of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 45 and d = - 30 - (- 45) = - 30 + 45 = 15, thus
= - 45 + 15(n - 1) = - 45 + 15n - 15 = 15n - 60
