Since E is a midpoint, we can set de and ef equal to each other to find the value of x.
6x = 3x + 6
3x = 6
x = 2
Then we can plug in x=2 and find that both de and ef are 12. Then since E is the midpoint of df, we can add de and ef to find the value of df.
12 + 12 = 24
Answer:
Step-by-step explanation:
From the given right angle triangle,
The hypotenuse of the right angle triangle is x
With ∠33 as the reference angle,
The adjacent side of the right angle triangle is 15
The unknown side is the opposite side of the right angle triangle.
To determine x, we would apply
the cosine trigonometric ratio.
Cos θ, = adjacent side/hypotenuse. Therefore,
Cos 33 = 15/x
x = 15/Cos 33 = 15/0.839
x = 17.9 to the nearest tenth
Answer:
X = 97.45 - 42
Step-by-step explanation:
If 42 + X = 97.45, X needs to be 97.45 - 42
you can do the same thing with smaller numbers, for example:
5 + X = 7
7 - 5= 2 and you can check for sure that this is the answer by adding them together 5 + 2= 7 so it's definitely the right answer
so for this question, 97.45- 42 = 55.45 so that's X
you can check that by 55.45 + 42 and if the answer is 97.45 that's the right answer!
I hope that makes sense
