Angle BEC is the unmarked angle in the middle of the figure. Its value is the difference between straight angle AED (180°) and the two marked angles, 57° and 33°. That difference is ...
... 180° - 57° -33° = 90°
∠BEC is a right angle.
3x4=12 gives him 12 baseballs. he has 5 fewer tennis balls than base balls so you subtract 5 from 12 and you get 7 tennis balls.
Answer:
x = 65
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180° for third angle
third angle = 180° - (60 + 55)° = 180° - 115° = 65°
65° and x are vertical angles and are congruent, thus
x = 65
The volume of the triangular prism is 66 cubic inches.
In order for us to know the volume of the triangular pyramid, first we need to know the ratio of the volume of triangular prism and the volume of the triangular pyramid.
Volume of the pyramid = 1/3 * volume of the prism.
Volume of the pyramid = 1 / 3 * 66
<span>Volume of the pyramid = 22 cubic inches.

So the volume of the triangular pyramid is 22 cubic inches.
