Group Title
Plane A which contains an isosceles right triangle forms a dihedral angle of 60 degrees with another plane B. if the hypotenuse of the triangle lies in plane B and measures 8 in., find the distance from the vertex of the right angle to plane B, and the length of the projection of each leg of the triangle on plane B.

So, it's dw:1353327509163:dw and dw:1353327558921:dw Now, first we'll need to find the length of the hypotenuse and vertex of right angle. That's done by using the tan 45. Now, we'll find the distance from the vertex of the right angle to plane B. Since we have the length, which will be \(4 \tan 45^o\), we'll apply the sine to find that length. It will be dw:1353327784152:dw i.e. (4 tan 45)(sin 60)

find the distance from the vertex of the right angle to plane B = 4 square root of 3 length of the projection of each leg of the triangle on plane B = 8 is this correct?? regardless of the unit

the first might be 2 sqrt 3 the second..hmm can i see your workings?

aaaawwww.. i was wrong.... what i did was the 306090 angles, but it should be 454590.. right?

4 tan 45 = 4 4 sin 60 = 2 sqrt 3?

please explain me this one "Plane A which contains an isosceles right triangle forms a dihedral angle of 60 degrees with another plane B." it's kinda confusing

It's the first pic. It means that the plane A is at angle of 60 with B

And on the plane A there is a isoscles right angle triangle.

is that the right position of the isosceles triangle?
 one year ago

Shadowys Group TitleBest ResponseYou've already chosen the best response.1
Yup. Since the "the hypotenuse of the triangle lies in plane B"

eroshea Group TitleBest ResponseYou've already chosen the best response.0
so where to put the imaginary line for this," from the vertex of the right angle to plane B" and "the length of the projection of each leg of the triangle on plane B."

eroshea Group TitleBest ResponseYou've already chosen the best response.0
and where is the 60 degree angle?? sorry if i have so many questions

where does projection of each leg of the triangle refers to??
 one year ago

Shadowys Group TitleBest ResponseYou've already chosen the best response.1
I was thinking that they refer to the same line actually...because the triangles projection is really that point.
