Answer:

x = 4 1/2

Step-by-step explanation:

To get to minus 1/2 from plus 2 you would subtract 2 1/2 from 2.

To arrive at x you would add 2 1/2 to 2.

The result is a progression of: 4 1/2, 2, - 1/2

(4 1/2 minus 2 1/2 = 2; 2 minus 2 1/2 = - 1/2)

KIM [24]

Answer with explanation:

The given expression is

$=2^5 \times 2^4$

→As, multiplication of real number follows Commutative property.

Which states that, if a and b are any two real numbers , then

a × b= b × a

The Expression equivalent to ,the above expression are

$1. 2^4 \times 2^5\\\\ 2. 2^5=32 \text{and} 2^4=16, \text{So} 2^5 \times 2^4=32 \times 16=512$

Solve for x I need help on this question

AlexFokin [52]

Answer:

$x\approx7.8$

Step-by-step explanation:

In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:

$sin(\theta)=\frac{opposite}{hypotenuse}$

$sin(23^\circ)=\frac{x}{20}$

$20sin(23^\circ)=x$

$x=20sin(23^\circ)$

$x\approx7.8$

Therefore, the length of the opposite side is about 7.8 units
