An isosceles triangle has two sides equal and two angles equal. It is given in the problem that ∠Y is equal to a². We can solve for the remaining angles and the solution is shown below:
180°=∠X+∠Y+∠Z
180°=∠X+a° +∠Z
180°-a°-∠Z=∠X
If ∠Z is the same with ∠Y, then ∠X is equal to 180°-2a°.

What is the area of the composite figure? ___ units^2
elena-14-01-66 [18.8K]

Answer:

  34 square units

Step-by-step explanation:

The figure can be considered to be a trapezoid with a rectangle removed.

The area of the trapezoid is ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(10 +6)(5) = 40

The area of the rectangle is ...

  A = LW

  A = (3)(2) = 6

Then the area of the shaded portion of the figure is ...

  shaded area = trapezoid area - rectangle area

  = 40 - 6 = 34 . . . square units

In geometry it is the shape made when a solid is cut through by a plane.

Example:

Part A: The name of the shape created by cross section of the prism is a square

<span>(We don't draw the rest of the object, just the</span><span> </span><span>shape</span><span> </span><span>made when you cut through.)</span>

<span>if Part B is a continuation from Part A then the shape of the resulting cross section would be a square.</span>

<span>if Part B is completely </span>separate<span> from Part A then the shape of the resulting cross section would be a rectangle.</span>

Since the wording is confusing I would, for part B, say that the shape of the resulting cross section is a rectangle regardless, because every square is always a rectangle but every rectangle is not always a square.

Part A- Square

Part B- Rectangle

Hello,

To answer your problem, use the Pythagorean Theorem for 2 right triangles and the Area of a Rectangle to find the Area of the Parallelogram.

All together:

A = 2(area of right triangle) + (area of rectangle)

A = 2[1/2*b*h] + [b*h]

To find the area of the parallelogram, I would be here for a while. Haha
