34 Use the pythagorean equation for a right triangle let x be one leg of the triangle, so the hypotenuse would be 2x +2 , and the other leg is 30 so using the equation we get: x2 + 302 = (2x+2)2 x2+900 = 4x2+8x+4 Rearranging, we get 3x2+8x-896 = 0 Using the quadratic equation we can solve for x, x = {-b +/- SQRT(b2-4ac)}/2a x = {-8 +/- SQRT(82-4(3)(-896))}/2(3) x = 16, and -18.667 but we can eliminate the negative answer so the hypotenuse will be 2*(16) + 2 or 34

If a right triangle has 60 degree angle and a length of 8 meters how do you find the hypotenuse?
As the relationship between the length and angle given are unclear a graphic explanation can be found at the link below
If the side opposite angle A of a right triangle is 30 meters and the hypotenuse is 90 meters what is the sin of angle a?
sin of angle a = opposite/hypotenuse = 1/3 sin-1(1/3) = 19.47122063 degrees
If this is opposite is 30 degree angle in a right triangle is 12.5 meters how long is the hypotenuse rounding to the nearest tenth?
If the angle opposite the side of 12.5 meters is 30 degrees then use the sine ratio to find the hypotenuse which works out as 25.0 meters.
