The three answers you have are correct. The last fourth answer is coincidentally "angle 4". If another number other than '4' was in the diagram, then you would label it as angle X (replace X with that number in question).
note: you can say "angle 4" or you can use the angle markers as you have been doing. It's probably best to stay consistent.
(1/3)r + (2/3)r = -2 -1
1r = -3
r = -3
Hope this helps
The range of the cubed root of x is all real numbers.
Graphically
The height of this function will start at - infinity and continue to infinity.
(look at the vertical growth of the graph. It will keep going down and will also keep growing forever)
Algebraically
Nothing will "break" this function as it is a cubed root. Thus the output (range) could be anything
<span>Opposite angles of a parallelogram are equal, so:
5x - 28 = 3x - 10
2x = 18
x = 9
Plug x = 9 into the equations
m angle 2 = 5x - 28 = 5 * 9 - 28 = 17
m angle 4 = 3x - 10 = 3 * 9 - 10 = 17
The sum of all angles in a parallelogram is 360,
and we know: m angle 1 = m angle 3, so:
m angle 1 + m angle 2 + m angle 3 + m angle 4 = 360
m angle 3 + 17 + m angle 3 + 17 = 360
2 * (m angle 3) = 360 - 17 - 17 = 326
m angle 3 = 163</span>
While neither 9 nor 8 are prime numbers, the factors of 9 are 3*3<span> and of 8 are 2*2*2. Since they share no factors in common, their product will be the least common multiple. (Multiples of 9 are 18, 27, </span>36<span>, 45, 54, 63, and 72; Multiples of 8 are </span>16<span>, </span>24,32<span>, </span>40<span>, 48, </span>56<span>, </span>64<span>, and 72).
