&the triangle is a right triangle. Does that mean all of the angles equal 90 degrees?

"Use your calculator to find tan 59. Use the resource page provided by your teacher and follow the instructions below to help you find out why that value appeared.

a) Each of you will work with a different size right triangle with a 59 angle at A. What are the measures of the other two angles?"

Picture this....a car stuck in the mud and a tree some distance away but exactly parallel. A man wishes to pull the car out of the mud by tying a rope to the tree and to the car. (It forms a v with the man at the tip) It requires a force of 10,000N to free the car from the mud. The man is capable of applying a maximum force of 1000 N. The theta angle I am trying to find is between the rope connected to the car and the imaginary line between the car and the tree....if you put a line on top of the v I mentioned earlier making it an upside down triangle....then theta would be the angle on the left.....please I'm not looking for just an answer...I want to know how to do this...I have worked for hours and all my answere do not seem right....thanks

Find the angle of intersection of the plane 3x + 3y -4z=-3 with the plane 3x-2y+3z=4

i've already found
n1 = <3,3,-4> & n2 = <3,-2,3>
cos(theta) = (n1*n2)/(|n1| |n2|)
theta = cos ^-1 (-9/sqrt(748))
in radians i get 1.9 and degrees i get 109
but when i type them in as answers i get it wrong.. what did i do wrong??

so there is a formula for the unknown diameter of field of view-

(magnification of "known" lense divided by maginification of "unknown" lense) times known diamter of f.o.v (field of view)

I know how to find the diamter of f.o.v by measuring it, and I know the "known" maginification (i set the scope to 40X), but what in the world is the "magnification of unknown lens"??

I have never done punnett squares and I do not know how to explain what I need. So heres my best shot I hope someone can help me!

Assume that “S” represents the dominant trait of having long leaves, and “s” represents the recessive short-leafed trait in a plant. In the parental generation, you cross a homozygous long-leafed plant with a homozygous short-leafed plant. Draw a Punnett square illustrating this cross, and give the genotypes and phenotypes of the F1 generation.

F1:AaBbCc x AaBbCc
