Step-by-step explanation:
Step 1: Identify Variables
Angle θ = 23°
Opposite Leg = x
Hypotenuse = 21
Step 2: Solve for x
Substitute in variables [sine]: [tex]\displaystyle sin(23^\circ) = \frac{x}{21}[/tex][Multiplication Property of Equality] Isolate x: [tex]\displaystyle 21sin(23^\circ) = x[/tex]Rewrite: [tex]\displaystyle x = 21sin(23^\circ)[/tex]Evaluate: [tex]\displaystyle x = 8.20535[/tex]Round: [tex]\displaystyle x \approx 8.2[/tex]Related Questions

Find the area of the figure.
The area is
square units.
Answers
Answer:
36 square units
Step-by-step explanation:
split the figure so that it's a triangle and a rectangle. Find the area of the rectangle (base x height or 6 x 4), which is 24 square units. Then, find the area of the triangle ((base x height)/2 or (6 x 4)/2), which would be 12 units. Then add those units up (24 + 12) and you get 36.

If a value of a car worth 50000 is deprecating half yearly at 10 percent pa the correct expression to express its value after 2 years is?
Answers
Answer:
50,000 x 0.90 ^ 4 = X
Step-by-step explanation:
Since the value of a car worth $ 50,000 is deprecating half yearly at 10 percent, the correct expression to express its value after 2 years is determined through the following calculation:
50,000 x 0.90 ^ 4 = X
32.805 = X
Thus, after 2 years with a semi-annual depreciation of 10%, the car will be worth $ 32,805.

Hypotenuse/leg = leg/part
Hypotenuse = 8 cm
Leg = z
Part = 6 cm
Plug in the values
[tex] \frac{8}{z} = \frac{z}{6} [/tex]
Cross multiply
[tex] z*z = 8*6 [/tex]
[tex] z^2 = 48 [/tex]
