sum of interior angle =n-2(180)
n is the number angles
5-2(180)
3(180)
=540
x=102+116+123+88=429
540-429=111
x=111
Answer: A
Step-by-step explanation:
Answer:
2, 120 degrees
Step-by-step explanation:
The first step in finding the polar form is finding the modulus, r
r= sqrt( x^2 + y^2)
r = sqrt( (-1)^2 + sqrt(3)^2)
r = sqrt(1+3)
r= sqrt(4)
r =2
The next step is finding the angle
theta = arctan (y/x)
theta = arctan (sqrt(3)/-1))
theta = arctan (-sqrt(3))
theta = -60
The point (-1, sqrt(3)) is in the 2nd quadrant, but our angle is in the 4th quadrant, so we add 180 degrees
theta = -60 + 180 = 120
theta = 120 degrees
Spinning on Y out of three letters (G, I and Y) = 1/3
then either an easy or hard = 1/2
so
The probability that the spinner will stop on the letter Y and then easy
= 1/3 x 1/2
= 1/6
= 0.17
answer:
0.17
Answer:
(-6,-1)
Step-by-step explanation:
let b be x2,y2
then apply mid point formula
x=(x1+x2)/2
y=(y1+y2)/2
