<h3>
Answer: x = 19.7 (choice C)</h3>
=========================================================
Explanation:
The reference angle is 24 degrees. Opposite that angle is the side 8 units long. The horizontal portion is unknown and it's the adjacent side.
Also unknown is the value of x which is the hypotenuse.
To summarize:
- opposite = vertical leg = 8
- adjacent = horizontal leg = unknown
- hypotenuse = x
The hypotenuse is always opposite the 90 degree angle.
To tie together the opposite and hypotenuse, we'll use the sine ratio
sin(angle) = opposite/hypotenuse
sin(24) = 8/x
x*sin(24) = 8
x = 8/sin(24)
x = 19.6687 approximately
x = 19.7 after rounding to the nearest tenth.
Side note: your calculator needs to be in degree mode
Answer:
The First One
Step-by-step explanation:
Try to substitute x by zero for example
(the minus will gone by zero)
You will get y = +2
and the graph you see the y =+2 !!
I hope that it's a clear solution and explanation.
Answer:
∠A=123°.
Step-by-step explanation:
From the given figure it is clear the CD and CE are two tangent lines on circle with center A.
Radius is perpendicular to the tangent at the point of tangency.
Smaller arc DE = (5x-2)°
It means central angle DAE is (5x-2)°.
Now, ADCE is a quadrilateral and sum of all angles of a quadrilateral is 360 degrees.
The value of x is 25.
Therefore, the measure of ∠A is 123°.
Answer:
That's a very dumb question, because some of her friends could be fakers and users. But, I'll answer it.
86 subtracted by 2 is 84.
It says she gave 3 to each friend so:
84 divided by 3 is 28.
She has 28 friends.
