Step-by-step explanation:
<u>Given:</u> XW is an altitude
m∠XWY=8x-6
<u>Prove:</u> x=2
<u>Solution:</u>
Statement Reason
1. XW is an altitude Given
2. m∠XWY = 90° Definition of altitude
3. m∠XWY = 8x - 6 Given
4. 8x - 6 = 90 Substitution property
5. 8x - 6 + 6 = 90 + 6 Addition property of equality
8x = 90
6. x = 12 Division property of equality

The perimeter of the entire figure is 62.8 cm.
Given, that the diameter of the inner semicircles is 9 cm and the width between the outer and inner semicircles is 2 cm.
The radius of the inner semicircle =4.5 cm and the radius of outer semicircle =5.5 cm (∵Diameter=9+2=11 cm)
We need to find the perimeter of the entire figure.
<h3>What is the perimeter?</h3>
A perimeter is a closed path that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
We know that, the circumference of a semicircle=πr and the circumference of two semicircles=2πr
Thus, the circumference of inner semicircles=2×3.14×4.5=28.26 cm
The circumference of outer semicircles=2×3.14×5.5=34.54 cm
The perimeter of the entire figure=28.26+34.54=62.8 cm
Therefore, the perimeter of the entire figure is 62.8 cm.
