Let
x--------> The number of red marbles
y--------> The number of blue marbles
we know that
equation
equation
equate equation and equation
therefore
the answer is
The number of red marbles is
The number of blue marbles is
Yes because of ASA
Angel MLX =angel JLM
JLM =90
They share a side (included ) so it is ASA
[c] 70°
40+2x=180
2x=140
x=70
i use 2x since the angle measures of D and C are equivalent since it is an isosceles
Angular speed is radians per second.
It covers pi/18 in 3.1 seconds.
Angular speed = (pi/18)/3.1
The area of a sector is = r(theta) with r radius and central angle theta being in radians, not degrees.
