Answer:
41°
Step-by-step explanation:
Supplementary angles are angles that has their sum total of angles as 180°.
If two angles ∠x and ∠ y are supplementary, this means
∠x+∠y = 180° ... (1)
Since ∠y = 139°, to get ∠x, we will substitute the value of ∠y in equation 1 to have;
∠x + 139° = 180°
∠x = 180°-139°
∠x = 41°
Therefore the measure of ∠x is 41°
When X=0, the function would be:
<span>f(x) = 4x^3 -20x2 + 24x
0= </span><span>4x^3 -20x2 + 24x ----->divide all by x
</span>x(4x^2 -20x + 24) =0 ------> split -20x into -12x and -8x
x(4x^2 -12x -8x + 24)
x{4x(x-3) - 8(x -3}
x(4x-8) (x-3)
x1= 0
x2= 8/4= 2
x3= 3
Answer:
x and y = 66.5
Step-by-step explanation:
180-47=133
133/2=66.5
Answer:
the measure of supplementary angles must add up to 180
Step-by-step explanation:
complementary angles add up to 90°
angles on a straight line are supplementary angles which add up to 180°
