Answer:
x = 23 degrees
Step-by-step explanation:
sin theta = opposite side/ hypotenuse
sin x= 9/23
Take the arcsin of each side
arcsin( sinx) = arcsin (9/23)
x = arcsin (9/23)
x=23.03568411
Rounding to the nearest degree
x = 23 degrees
Answer:
The figure will result is cone ⇒ B
Step-by-step explanation:
<em>When a </em><em>right triangle is rotated about its vertical leg 360°</em><em>, then it formed </em><em>a cone</em><em> its radius is the horizontal leg of the triangle and its height is the vertical lege of the triangle</em>
<em />
In the given figure
∵ Triangle TRE is a right triangle
∴ The horizontal leg is RE
∴ The vertical leg is TR
∵ The triangle is rotated around the horizontal leg RE 360°
∴ It formed a cone its radius = TR and its height = RE
∴ The figure will result is the cone
Every whole number<span> is a </span>rational number: for example, 3=31. ... Everywhole number<span> n can be written as a fraction of integers: n=n1. We aren't required to write it that way; we just need to know that it is possible to express every </span>whole number<span> as a fraction of integers, and hence it is </span>rational<span>.
So I Believe the Correct Answer would Be D)</span><span> If a number is not a rational number, then it is not a whole number. The converse is true</span>
The perimeter is the distance around the object so you add 4+10+4+10 to get
28 inches as the perimeter of the rectangle
