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}.

Answer:
80 students
Step-by-step explanation:
52 + 28 = 80
So in every 5 people, theres 1 left and 4 right.
so therefore there is 25 right handed people and 5 left handed people
Answer:
28
Step-by-step explanation:
7 x 4 = 28
hopefully this helps you :)
pls mark brainlest ;)
Answer:
The standard form of line is

Step-by-step explanation:
we are given a line
slope=3
so,

y-intercept of -2
so,

now, we can use slope-intercept form of line

now, we can plug values

we can write it in standard form of line


we can subtract both sides by 3x



So, the standard form of line is
