Answer:
Step-by-step explanation: These points are the only points with integer coordinates that satisfy a set of
inequalities.
Write down these three inequalities.
Answer:
X = 66
Step-by-step explanation:
A straight line is equal to 180 degrees so if you have one side of that line you can figure out the inside angle.
Now that you have two of the angles inside the triangle add them up. All the interior angles of a triangle will add to 180. So add up 38 and 76 to get 114. Now do 180 - 114, you should get 66
so x = 66
Answer:
y = - c/B + Ax/B
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
To understand the problem clearly, you have to illustrate it. Based on my understanding, the problem goes like this. Please refer to the picture. When the sun is high up in the sky, it causes a shadow to form. In the picture, this is represented by the bold horizontal line to the ground that measures 27.6 m. You want to find the angle of elevation of the sun, denoted as x°. With the height of the tree being 18 m, you create a right triangle. Therefore, we can apply the pythagorean theorems.
With respect to the unknown angle, you know the opposite side (18 m) and the adjacent side (27.6 m). So, it would be easier to use the tangent function.
tan x° = opposite/adjacent = 18/27.6
x = tan^-1 (18/27.6)
x = 33.11°
