e-lub [12.9K]

Answer:

$x=36.772$

Step-by-step explanation:

Given : Expression $x=25.36+0.45(25.36)$

To find : Solve the expression ?

Solution :

Step 1 - Write the expression,

$x=1(25.36)+0.45(25.36)$

Step 2 - Apply distributive, $ab+ac=a(b+c)$

Here, a=25.36, b=1, c=0.45

$x=25.36(1+0.45)$

Step 3 - Solve the expression,

$x=25.36\times 1.45$

$x=36.772$

Therefore, $x=36.772$

What is the value of x?

Lunna [17]

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
