What is a 30-60-90 triangle?The 30-60-90 triangle is called a special right triangle as the angles of this triangle are in a unique ratio of 1:2:3.
According to the given sum:
In theory, we know,
For a 30-60-90 triangle, the sides opposite to 30° is x , side opposite to 60° is x*[tex]\sqrt3}[/tex] and the side opposite to 90° is 2x
Therefore,
If x = 1,
The sides are [tex]\sqrt{3},2,1[/tex] where,
perpendicular = [tex]\sqrt{3}[/tex]
Base = 1
Hypotenuse = 2
We know sinФ = [tex]\frac{perpendicular}{Hypotenuse}[/tex]
But in the case of sin30 , we have to take perpendicular as 1 and hypotenuse as 2, that is the angle has to be at base. If it was sin60, we would have taken perpendicular as [tex]\sqrt{3}[/tex] and hypotenuse as 2.
Therefore,
Sin30 = [tex]\frac{1}{2}[/tex]
Hence, we can conclude that the value of sin30 is [tex]\frac{1}{2}[/tex].

I have a question that says " jada has read 3/5 of a book. She has read 75 pages so far. How many pages are in the whole book?" (I NEED HELP)
Answer and Step-by-step explanation:
To solve, we would multiply by the reciprocal of the portion Jada has read, and multiply that number to 75.
The reciprocal means the the value, but flipped, so [tex]\frac{3}{5}[/tex] will become [tex]\frac{5}{3}[/tex].
Now we do 75 times [tex]\frac{5}{3}[/tex]/
[tex]\frac{75 * 5}{3} \\\\\\\\\frac{375}{3} \\\\\\\\125[/tex]
So, there are 125 total pages in the book.

11) x = 145°
12) x = 40°
Step-by-step explanation:
9) 180-91 = 89
10) x = 118° because it is alternate interior to 118
11) x-30 = 115, x = 145

find the value of x. Round to the nearest degree
Answer:
51 degress
Step-by-step explanation:
sin x = 7/9
x = sin^-1 (7/9)
simply using a calculator.
Answer:
x = 51 degrees
Step-by-step explanation:
(to find x, use sine)
Sine = [tex]\frac{opposite}{hypothenuse}[/tex]
⇒ Sine x = [tex]\frac{7}{9}[/tex]
⇒ [tex]\frac{7}{9}[/tex] = 0.78
⇒ Sine x = 0.78
then calculate what Sine-1 of 0.78 is:
⇒ Sine-1 of 0.78 = 51.26
x = 51.26
Round to the nearest degree:
51.26 ⇒ 51 degrees
If 'a' is an odd number, which of the following is also odd?
3a + 1
о
a + 2
O +
2a + 2
a + 1
=================================================
Explanation:
Adding an even number to an odd number always results in an odd number
even + odd = odd
odd + even = odd
So if 'a' is odd, adding 2 onto it (even number), leads to an odd result of a+2.
----------------------------------
Extra Information (optional section)
If you are curious why the two equations shown above are true, then here's a proof.
Let 'a' be an odd number. This means a = 2k+1 for some integer k. We add 1 to any multiple of 2 and it goes from even (2k) to odd (2k+1).
If we made b an even number, then b = 2m for some integer m.
Adding 'a' and b gives us...
c = a + b
c = ( a ) + ( b )
c = ( 2k+1 ) + ( 2m )
c = (2k+2m) + 1
c = 2(k+m) + 1
c = 2n + 1 .... where n = k+m
The result a+b is an odd number since it is in the form 2*(integer)+1
It verifies the claim that odd+even = odd.
So this shows that a+2 is also odd, since we let b = 2.

The surface area of the rectangular prism 158 square feet.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any object is called the surface area.
The rectangular prism will have six faces. The surface area will be calculated as:-
Surface area = 2 ( 3x5) + 2 ( 8x3) + 2(8x5)
Surface area = 30 + 48 + 80 = 158 square meters
Therefore the surface area of the rectangular prism is 158 square feet.

La senora carmen pidio un prestamo en cierta financiera de $3,000 con un interes mensual del 8% y quiere saber cuanto debe pagar en total al termino de 3 meses
Responder:
$ 3720
Explicación paso a paso:
Dado que:
Tasa mensual, r = 8%
Principal, P = $ 3000
Duración o período, t = 3 meses
La cantidad final, A, que pagará después de 3 meses:
Usando la fórmula de interés simple:
A = P (1 + rt)
A = 3000 (1 + 0,08 * 3)
A = 3000 (1 + 0,24)
A = 3000 (1,24)
A = $ 3720

Substitution or Elimination?
Answer:
(x, y) = (18/5, 2/5)Step-by-step explanation:
x + y = 4
x = 4 - y
2x - 3y = 6
Substitution x2x - 3y = 6
2(4 - y) - 3y = 6
8 - 2y - 3y = 6
-5y = 6 - 8
-5y = -2
y = 2/5
