Answer:
The side opposite 30 is 9 ft.
The side opposite 60 is 15.59 ft.
Step-by-step explanation:
Below are pictures of how I got the answer.
I will provide steps to accompany each corresponding picture to further explain what I am doing.
1. This picture simply illustrates what the triangle looks like. The Hypotenuse is 18, as described in the problem.
2. I am showing how the sin will work. What is the opposite side and what is the hypotenuse. I picked this particular angle because it allow me to divide it by a number I already have, 18. I show that sin of 30 is 0.5
3. Now, we know what the side value is, 9. We can easily find the remaining side using Pythagorean theorem.
9^2 + y^2 =18^2
81 + y^2 = 324
y^2 = 243
y = 15.59
Answer:
X intercepts are points where a function intersects or cuts through the x axis where y=0.
Step-by-step explanation:
In the function given which is f(x) =x^2 +4x + 3 we see that this is a parabola of which when the graph is drawn it has a U shape so when finding x intercepts of this function it is those points on the function where the graph cuts the x axis and at those two points f(x)= 0, so here Mathieu had made a mistake of factorizing and equating the x intercepts for this function.
For finding the X intercepts let f(x) = 0
therefore 0= x^2 + 4x + 3 now we solve for x
0= (x+1)(x+3)
(x+1)= 0 or (x+3)=0
therefore x=-1 or x=-3
now if you substitute these values onto the function they give f(x)= 0,
f(-1) = (-1)^2 + 4(-1) + 3 = 0
f(-3) = (-3)^2 + $(-3) + 3 =0
now let us look at Mathieus answer which is x+1 = x+3 yes these x values do give the same y value but they are not equal because if you can actually solve this further you would not get a defined answer. Both these are factors of the function but are not actually equal as the function would not be able to be drawn if this was the case.
I believe it's 36. The vertices have the same x coordinate so I found the difference between the y coordinates.
Answer: X= 54.9 mm
Explanation: honestly I would never know how to do this and I don’t know how to do this I just put it into a triangle generator and it gave me the correct answer I promise its right
