Question

Find the value of x and y.

Answer 1

for the first one... you use pathgyreon's theorem... a^2+b^2=c^2

Answer 2

since it is a perfect square, both sides are 45... 45^+45^2=4050.... square root of 4050 is 63.63961

Answer 3

45^2+45^2=4050... rather

Answer 4

the second one... the left triangle is half of a perfect square... 90 degree corner with 2 45 degree corners is 180 degrees

Answer 5

so, you know the 2 legs are the same

Answer 6

you can say x^2+x^2=square root(8)

Answer 7

so your legs are 2^(1/4) each

Answer 8

then you have to use trig to find the other angle and legs on the right triagle... AAS and AAA formulas, i dont remember those... they'r eonline somewhere or in your book, should be fairly easy to compute

Answer 9

third is practically the same, you have 3 right triangles interlocked, you have angles (45 and 90 degree)

Answer 10

use your AAS formula
