Answer:
Step-by-step explanation:
To find the surface area of a composite 3D figure, add the areas of each geometric figure making up the composite 3D figure. To find the volume of a composite 3D figure, draw any necessary planes to view the figure as basic three dimensional figures, then: add basic figure volumes belonging to the composite shape.

Answer:
x = 8°, y = 86°
Step-by-step explanation:
the other base angle inside the triangle must be 'y' as well because two sides are congruent
y = 180-94 or 86°
x = 180-(2x86) = 180 - 172 or 8°
Answer:
A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
