Reposting because it has gone down to the second page! Evaluate 1. sin(tan inverse sqrt(x^2-2x)) 2. tan (sec inverse 3y) For 1. draw a right triangle and label the opposite leg sqrt(x^2-2x), the adjacent side 1 and the hypotenuse x-1. Do the calculations to see why this is so...

Two sides of a triangle are 15 and 20 feet in length. How fast is the third side increasing if the angle between the given sides is 60 degrees and is increasing at a rate of 2 degrees per second.

Yesterday I learned to solve a right triangle assuming I know the 3 angles and 1 side. I can now establish the lengths of the 2 other sides using a sine table I printed off the net. Today I hope I will learn to solve a right triangle but now I only know 1 angle (the right ...

If one angle and two sides of a triangle are given, how to find the third side? This is for solving a 9th grade geometry problem of finding the distance from earth to venus You can use a standard formula for the side of the triangle that must be mentioned somewhere in your ...

third side (picture attached)
I have already asked this in another thread. Here is more explanation: The radius of earth's orbit is 1.5 * 10^8km & the radius of venus's orbit is 1.1 * 10^8 km. We need to find out the distance from earth to venus for both positions of venus. A picture is uploaded here if ...

Third Side, Reply to Jen
Hi Jen, I've seen the drawing. My site is down at the moment. Draw a line from Venus (either of the two positions) to the line Earth-Sun at right angles. Let's call the distance Earth Venus d. Then you have a right angle triangle with a hypotenuse d, the line that intersects ...

The measures of two sides of a triangle are 9 and 15. Use an inequality to express the range of the measure of the third side,m.

An isosceles right triangle has an area of 98cm squared. Find the length of each leg. The formula of finding the area of a triangle with one right angle is: (b x h)/2 You know that an isoceles triangles has two equal sides. Those equal sides are the base and height. This means...

If two sides of a triangle have lengths 4 and 9, then the length of the third side may be any number a) less than 13 b) greater than 5 but less than 13 c) greater than 4 but less than 9 d) greater than 5 I suggest you draw this. It is not d, nor a. it is b. Am I correct? yes ...

What is the converse of the theorem statement: If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. If two sides of a triangle are divided in the same proportion, then the line connecting the dividing points...

What is the converse of the theorem statement: If a line divides two sides of a triangle proportionally, then it is parallel to the third side. see the other post.

What is the converse of the theorem statement: The segment connecting the midpoints of two sides of a triangle is parallel to the third side and is half as long.

related rates with work shown
this is a relate rates problem in calculus in a right triangle, the hypotenuse is 5 and the vertical side is x and the angle is theta. so if theta increases at a constant rate of 3 radians per minute, at what rate is x increasing in units per minute when x equals 3 units? d(...

I hope that the diagram I have drawn for myself matches the one in your question. I have a triangle with sides 20 and 10 and an angle of 120º between them By the cosine law I found the third side to be 26.4575. You said you found the maginitude, I hope we match. After that, ...

To reduce the loading from snow on the roof, a ski chalet design calls for the roof slope to be 36 degrees from vertical. If the width of the base is 14.0 m, what is the slant height of the roof? - Basically, I'm having some trouble with the terms and not getting the question...

You probably were messed up by the angle(distance) c being wanted rather than a as the law is usually written. Best to remember it using this picture in your head: cos side unknown = cos other side*cos third side + sin other side*sin third side* cos angle opposite unknown side
