Answer:
I guess they subtracted a 110 from -110 instead of subtracting from 360
Answer:
Approximately 23.6
Step-by-step explanation:
So first find the fraction of the whole circumference the arc is.
270 ÷ 360 = 0.75
The circumference is 10π
0.75 * 10π = 7.5π
7.5π = 23.5619449019 ≈ 23.6
Answer:
y-6=1/2(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
y-6=1/2(x-4)
The value of y from the given trig expression is pi/3 rad
<h3>Trigonometry identity</h3>
These identities are expressed in terms of sine, cosine and tangent
Given the expression

Expand sin(x+y)
sin(x+y) = sinxcosy + cosxsiny
Compare both equations
cosy = 1/2
y = arccos(1/2)
y = 60 degrees
y = pi/3 rad
Hence the value of y from the given trig expression is pi/3 rad

Janice is currently 4.
In 12 years, Janice will be 16, and 2 years ago she was 2. That being said, 16 is eight times more than 2, thus meaning she is currently 4 years old.
I hope this helps!
