<h2>The missing measures of the angles are:</h2>

<u>Given</u>:

<em><u>Note the following:</u></em>
- An equilateral triangle has all its three angles equal to each other. Each angle =
.
- This implies that, since
is equilateral, therefore, 
- Base angles of an isosceles triangle are congruent to each other.
- This implies that, since
is isosceles, therefore, 
Applying the above stated, let's find the measure of each angle:
- Find

(an angle in an equilateral triangle equals 60 degrees)
- Find




- Find
and
(base angles of isosceles triangle WZY)


(base angles of isosceles triangle are congruent)
Therefore,

- Find


Substitute

The missing measures of the angles are:

Answer: You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole
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


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


The volume of composite figure is


It can be written as

Therefore, the correct option is A.
