Answer:

82 degrees

Step-by-step explanation:

1. Measure of angle BAD + ABC = 180 degrees (definition of a parallelogram). Because ABC = 71, and CAD = 27, you get BAC + 71 +27 = 180. --> BAC = 82 degrees

2. BE * 2 = BD. This means that 2(2x+2) = 5x-3. This means 4x + 4 = 5x-3, which makes x = 7. AC = 2AE, which means that 2(4x-6) = AC, which means AC is 2(28-6), which makes AC = 44.

3. Because MNPQ is isosceles, NMQ = PQM. This also means PQM +NPQ = 180. NMQ = 30 +32 = 62. This makes NPQ + 62 = 180. NPQ = 118

Which expression represents the volume, in cubic

muminat

Given:

The composite figure.

To find:

The volume of the given composite figure.

Solution:

Given composite figure contains a cuboid and a pyramid.

Length, breadth and height of the cuboid are 8, 6 and 4 respectively.

Volume of a cuboid is

$V_1=length\times breadth\times height$

$V_1=(8)(6)(4)$

Length and breadth of the pyramid is same as the cuboid, i.e., 8 and 6 respectively.

Height of pyramid = 10 - 4 = 6

Volume of a pyramid is

$V_2=\dfrac{1}{3}\times length\times breadth\times height$

$V_2=(\dfrac{1}{3})(8)(6)(6)$

The volume of composite figure is

$V=V_1+V_2$

$V=(8)(6)(4)+(\dfrac{1}{3})(8)(6)(6)$

It can be written as

$V=(\dfrac{1}{3})(8)(6)(6)+(8)(6)(4)$

Therefore, the correct option is A.

It would be 2.4 times 10. I got this answer because there is 24 shaded in, so I divided it by 10 and got 2.4. The other answers could also be 6 times 4, 8 times 3, 2 times 12, 1 times 24. I hope this helps. <3
