Answer:
149.88
Step-by-step explanation:
If two line crosses, then the vertical angles are the angles opposite each other. In this way, these angles share the same vertex. So, the vertical angles are always equal. Therefore, in this problem, the right answers are:
1. ABE and CBD
Notice that the vertex is B, so these two angles share the same vertex. Accordingly, these two angles are vertical angles.
2. ABC and EBD
The same reasoning is applied here. The vertex is also B. Notice that <em>the angles CBD and ABD add up to 180 degrees. </em>
D) 5
3(x + 2) + x = 2x + 16
Distribute the 3 to the (x + 2)l
3x + 6 + x = 2x + 16
4x + 6 = 2x + 16
Subtract 2x and 6 from each side.
2x = 10
Divide each side by 2
x = 5

Answer:
5/2
Step-by-step explanation:
The multiplicative inverse is what me need to multiply by to get 1
2/5 * what = 1
Multiply by the reciprocal
5/2 *2/5 * what = 1 *5/2
what = 5/2
The multiplicative inverse is 5/2

The answer is given below
Step-by-step explanation:
The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
Substituting:
The volume of the frustum is given by the formula:
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
