Let O be the center of a circle. If <span>the measure of arc RS is 84 degrees, then m∠SOR=84^{0}. The triangle SOR is isoscales (because SO=OR as radii), so m∠RSO=m∠ORS=(180^{0}-84^{0}):2=48^{0}.
</span>
Line RU is tangent to the circle in point R, this means that m∠ORU=90^{0}.
Consider the triangle SRU. m∠RSU=30^{0} and m∠SRU=48^{0}+90^{0}=138^{0}, then m∠RUS=180^{0}-30^{0}-138^{0}=12^{0}.
ANSWER: Correct choice B - 12^{0}.

Yes.
When you divide the top and bottom of 2/8 by 2 you will get 1/4 which is the same as 1/4.

Answer:
$31,341.81
Step-by-step explanation:
The compound amount equation is A = P(1 + r/n)^(nt), where P is the unknown principal, r is the annual interest rate, n is the number of compounding periods per year and t is the number of years. We want to solve this for P:
A
------------------- = P
(1 + r/n)^(nt)
Substituting the given numerical values;
$45,000
--------------------------- = P
(1+0.073/4)^(4*5)
Using a calculator, we evaluate this expression, obtaining: $31,341.81
Answer:
f(x)=2sqrt( x + 3)
Step-by-step explanation:
We know it's a square root function because of the shape of the graph and it's moved to the left by 3 unit, so it has a d value of +3. We know it doesn't have a c value because it doesn't have a vertical translation as it's still at 0. For the a value, you can figure it out my substituting the graph points in and the values you know now then isolating and solving for the a value.
