What is area of a square the length of whose diagonal is 12?
The area is 72 square units. Explanation: the diagonal,d, is the hypotenuse of a rt. triangle whose legs are both s, the side of the square, so d2= s2 + s2 = 2s2 Therefore , the area of the square , s2 = d2/2 = (12)2/ 2 = 144/2 = 72.
The hypotenuse of a right triangle is 25 cm long One leg is 17 cm longer than the other Find the length of the shorter leg?
Call the length of the shorter leg s. Then, from the Pythagorean theorem, s2 + (s + 17)2 = 252. Expanding the binomial results in: s2 + s2 + 34s + 172 = 252, or 2s2 + 34s + 289= 625, or s2 + 17s - 168 = 0. This can be factored into: (s + 24)(s - 7) = 0, which is true when s = -24 or 7. Only the latter answer makes sense for a physical triangle; therefore, the shorter leg of this triangle is 7 cm long.
How do you solve 2 sin squared theta equals 1?
first divide each side by 2 so you get... sine^2(X)=1/2 Then make sine ^2(X)=sine(x^2) SO you get... sine(X^2)=1/2 Then take the sine^-1 of each side it will look like this X^2=sine^-1(1/2) type the right side into a calc which will give you a gross decimal but it works (0.5235987756) so now you have X^2=0.5235987756 then take the square root of each side to make it linear and you will get X=.7236012546 and that is your answer!!!! make sure to check it on your calculator...I did and it worked * * * * * Not quite correct, I fear. Try this: Let s = sin θ. Then, 2s2 = 1; s2 = ½; and s = ±½√2. Therefore, θ = 45°, 135°, 225°, or 315°; or, if you prefer, θ = ¼π, ¾π, 1¼π, or 1¾π.
