The value of x in the given diagram is 10
<h3>Similar triangles </h3>
From the question, we are to determine the value of the side labeled x
First, we will find the value of side |BC|
By the <em>Pythagorean theorem</em>, we can write that
|BC|² = 12² + 16²
|BC|² = 144 + 256
|BC|² = 400
|BC| = √400
|BC| = 20
Now,
Since ΔABC and ΔDEF are similar, we can write that
|BC| / |EF| = P ΔABC / P ΔDEF
But,
P ΔABC = 12 + 16 + 20 = 48
Thus,
|BC| / |EF| = P ΔABC / P ΔDEF becomes
20/ |EF| = 48/24
20/x = 2
x = 20/2
x = 10
Hence, the value of x in the given diagram is 10

Step-by-step explanation:
the slower plane traveled x miles in 4 hours.
the faster plane traveled x + 4×80 = x + 320 miles in 4 hours.
so,
x + x + 320 = 3800 miles
2x =3480 miles
x =1740 miles (in 4 hours) .
that means the slower plane's speed was 435 mph.
and the faster plane's speed was 435 + 80 = 515 mph.
Answer:
20.4
Step-by-step explanation:
If you are using D = r × t
10.2 = 0.5(t)
10.2/0.5 = t
20.4 = t
Answer: Line DE is the adjacent while line EF is the opposite.
Step-by-step explanation: This is a right angled triangle and the reference angle has been marked at point D. If you drew a line from that angle it would touch the triangle at line line EF. It’s facing the reference angle and that’s why it’s called the “opposite.”
The line that lies between the reference angle and the right angle is called the adjacent and that’s line DE in this triangle. The hypotenuse has already been identified for you, and that’s the line that’s opposite the right angle (it’s always the longest side).
**Please note that the opposite and adjacent ALWAYS depends on where the reference angle is positioned.
