1/5 x 25X - 1/5 x 75 + 9= 1/4 x 8X + 1/4 x 36
5X - 15 + 9 = 2X + 9
5X - 2X = 9 - 9 + 15
3X = 15
X= 15/3 = 5
Answer:
10.9
Step-by-step explanation:
You can solve this using the Pythagorean theorem, a^2+b^2=c^2, since it will form a right triangle.
You aren't missing the hypotenuse (c), but one of the side lengths (b). But you still solve like a normal algebraic equation.
Plugging in your values, you should start with 5^2+b^2=12^2
Then square everything.
25+b^2=144
Take away 25 from both sides.
b^2= 119
Then square root both sides.
b= 10.9
