Since she cooked 3/4 of the white rice, there is 1/4 of the white rice that is not cooked. This is equal to 2/8. 2/8+3/8=5/8. This shows that 3/8 of the rice that she bought was cooked. Please mark Brainliest!!!
The cos(C) =

we first need to find the actual lengths of the sides.. to do this we will use the Pythagorean theorem:
(x + 15)² + (x + 1)² = (x + 17)² and now after simplifying both sides and moving everything to one side we get the following quadratic equation:
x² - 2x - 63 = 0 and solving by factoring we get solutions of x = 9 and x = -7, but x = -7 does not make sense in this problem.
Using x = 9 we see the sides of the triangle are 10, 24, and 26
the cos(c) =

which is about 0.9231
