For this case, the first thing you should do is know that the measurement of a television is given by the diagonal of the television.
Therefore, to find the value of x, we use the Pythagorean theorem.
We have then:
Rewriting we have:
Then the dimensions are given by:
Answer:
the dimensions of the screen are: 33.6* 25.2
Answer:
Step-by-step explanation:
Triangle XYZ is a right angle triangle.
From the given right angle triangle
XZ represents the hypotenuse of the right angle triangle.
With ∠34 as the reference angle,
YZ represents the adjacent side of the right angle triangle.
XY represents the opposite side of the right angle triangle.
To determine x, we would apply the Cosine trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 34 = x/28
x = 28Cos34 = 28 × 0.8290
x = 23.212
To the nearest tenth, it becomes
23.2
<span>9x-y=5
rewriting the eqn in the form y = mx+b we get
y = 9x- 5
slope = 9</span>
Answer:
7 and 9
Step-by-step explanation:
The tenth place is where the 7 is.
0.7
If the number behind it is over 5, we round up. If it isn't, we round down.
0<5
We round down.
2.7 is the answer.
I hope this helps!
