Theta has a reference angle of 30° and is in Quadrant I or II.
Sin(theta) = ½
Basic angle: 30
<h3>What is the reference angle?</h3>
The acute angle between the terminal arm/terminal side and the x-axis. The reference angle is always positive. In other words, the reference angle is an angle sandwiched between the terminal side and the x-axis.
Angles: 30,
180-30 = 150
Because sin is positive in quadrants 1 and 2.

Answer:
39
Step-by-step explanation:
If x=1, then it's equal to 140/(1+9, or 10)+(1+4, or 5)^2, and that is equal to 140/10+5^2, or 140/10+25, and 140/10=14, and 14+25=39

Answer:
the total cost of the bike including modifying cost is $24,150
Step-by-step explanation:
⇒ bike cost: $21,000
⇒ 15% of $21,000 is 0.15 x 21,000 = 3,150
⇒ initial + additional cost: $21,000 + $3,150 = $24,150

(3a^2 - 3b)(2a^2 - b)
3a^2(2a^2 - b) - 3b(2a^2 - b) =
6a^4 - 3a^2b - 6a^2b + 3b^2 =
6a^4 -9a^2b + 3b^2 <===
