Answer:
Domain = {-6, -2, -1, 3, 5}
Step-by-step explanation:
The domain represents the input or x values of a given relation.
In the given set of ordered pairs: (-2, 4) (-6,8) (3,6) (5,15) (-1, 4)
Domain (input/x values) = {-6, -2, -1, 3, 5}
Range (output/y values) = {4, 6, 8, 14}

Option B) Acute
we know that
if a triangle contains an obtuse angle, then the other two angles must be acute.
<em><u>Verify</u></em>
The sum of the interior angles of a triangle must be equal to 180 degrees
in the triangle of the figure
113°+15°+x°=180°
Solve for x
118°+x°=180°
x=180°-118°=62°
62° < 90°
therefore
The angle x is an acute angle
