Liula [17]

Answer:

11/2

Step-by-step explanation:

$\frac{ {x}^{2} + {y}^{3} }{2 + x} \\$

when,

$x = 6 \\ y = 2$

Now substitute the value we get,

$\frac{ {6}^{2} + {2}^{3} }{2 + 6} \\ \\ = \frac{36 + 8}{8} \\ \\ = \frac{44}{8} \\ \\ = \frac{11}{2}$

The measure of an angle is 6 greater than half the measure of it’s supplement. Find the measure of the angle

viktelen [127]

Answer:

64°

Step-by-step explanation:

Set the measure of the original angle as x.

The measure of its supplement would be 180-x.

Thus,

x = 0.5 * (180-x) + 6

x = 90 - 0.5x + 6

1.5x = 96

x = 64°
