The correct answer is B) 50.

Straight lines add up to 180 degrees. The outside angle measurements given would tell us that the two known angles are 40 (180-140=40) and 90 (180-90=90). Since triangles must add up to 180 degrees, we take 180-90-40= 50, which is the measure of the missing angle.

What is the height of a triangular prism that has a height of 9 meters and a base with the following deminsions 4m 14m
Andrew [12]

Answer:

252m^3

Step-by-step explanation:

A solid having a triangular base is what we call a triangular prism. For every prism, its volume is always equal to the area of its base times its height. In other words:

V = AxH

V - volume

A- area

H - height of prism

We know that:

h = 4 m (side of base)

b = 14 (other base side)

A = bh/2 = 14x4/2 = 28 m^2

And then: V = A x H = 28 x 9 = 252 m^3

Answer: They are not congruent.

Step-by-step explanation:

You need to find the distance between these points to find congruence. If just one of these doesn't match with its corresponding side, its not congruent.

DE: square root of 68

_

GH: square root of 53

DE and GH are corresponding, but they are not congruent so these polygons are not congruent.
