SOLUTION:
Case: Trigonometry
Method:
Let the distance between the Sun and the Earth be 'z'
The relationship between x, y and z is:
Final answer:
In sentence,
The distance between the Sun and the Earth is the product of the distance between the Earth and the moon and the cotangent of the angle x formed using the lines from the Earth and the moon.
Right triangle
so
n + n + 40 = 90
2n = 50
n = 25
answer
Measure of angle n = 25°
Answer:
3/1 is the slope.
Step-by-step explanation:
Slope formula: y2 - y1/x2 - 1
Plugging in the given values, we get:
-9 - (-6)/3-4
-3/-1
Two negatives cancel each other out, so:
3/1 is the slope.
Help you answer the questions, sure! Do the problems for you, nope.
in Problem 26 you have 2 small triangles. In the left one you have the angle 36 degrees, which means that the other acute angle is 90-36, or 54 (degrees). You'll need to find the height of the left triangle; finding that height is the same as determining the length of the side adjacent to the 36 degree angle.
Let that height be repr. by h.
Then tan 36 deg = h/21 Use the inverse tangent function to find the value of h.
Look at the triangle on the right. It has a 42 deg angle, and the length of the side next to it is h (which you found above). x is the hypotenuse.
Can you see that x*cos 42 deg = h? Knowing h, can you now find x?
If you have any qu. about this approach, please ask questions.
(h+b) divided by 5. First find the sum of h and b then divide by 5 for the groups.
