Answer:
8.94 m
Step-by-step explanation:
Use the Pythagorean Theorum - 
. Use leg 1 as <em>a</em>, leg 2 as <em>b</em>, and the third side as <em>c</em>.
We know leg 1 is 4, and that leg 2 is twice as long as leg 1...
Now, we use the Order of Operations to find 
...
Now, we find the square root of to find c...
So, the length of the third side is 8.94 m.
Answer:
32.78
Step-by-step explanation:
Assuming that we have two right triangles joined together, with one having adjacent side a, with a side of 12 ft opposite reference angle 30°, and the other one having adjacent side b, with a side of 12 ft opposite reference angle 45°. Thus, a + b = length of AC.
Let's find a and b.
Finding a:
Reference angle = 30°
Opp = 12 ft
Adj = a
Using trigonometric ratio formula, we have:
tan(30) = 12/a
Multiply both sides by a
a*tan(30) = 12
Divide both sides by tan(30)
a = 12/tan(30)
a = 20.78 (nearest hundredth)
Finding b:
Reference angle = 45°
Opp = 12 ft
Adj = b
Using trigonometric ratio formula, we have:
tan(45) = 12/b
Multiply both sides by a
b*tan(45) = 12
Divide both sides by tan(45)
b = 12/tan(45)
a = 12
Length of AC = 20.78 + 12 = 32.78
