Answer:
A. 1/2.
Step-by-step explanation:
The ratio of the sides of a 30-60-90 triangle is 2:1:√3 where 2 is the hypotenuse. 1 is the shortest leg and √3 is the longest leg.
In the diagram we see that the longest leg is opposite the 60 degree angle.
So the longest leg is 3.5√x and the shortest leg ( from applying the ratios) = 3.5√x / √3.
and the hypotenuse is 2 * 3.5√x / √3 (using the ratios again).
So sin 30 = shortest leg / hypotenuse = 3.5√x / √3 / 2 * 3.5√x / √3
= 1/2.
Answer:
(-2, 0)
Step-by-step explanation:
The x-intercept is where the line meets the x-axis, so that is (-2, 0).
The domaine of a functions is the set of the values wherein the function is defined, or the set of the values that the function may take. The range is the image of the function.
Answer A is correct.
C and D are correct too by the definition of the inverse functions.
F is a correct answer.
The answer is D 5.48*10-8

Answer:
D. AB/CE = ED/BC
Step-by-step explanation:
In this question you apply the side-Angle-side similarity property that makes the two right triangles similar.
In this property, the lengths of the corresponding legs of the two right triangles are proportional.
Hence
Leg AB corresponds to leg CE
Leg ED corresponds to leg BC
From the property;
