Use the Pythagorean Theorem (a^2+b^2=c^2). Plug in the values in the equation. The hypotenuse is always c, so put 50^2 as your hypotenuse. Proceed to put 30^2 as any leg. Now, the equation is a^2+30^2=50^2. In order to isolate a, you must use the reverse of PEMDAS. 50^2-30^2=a^2. This equates to 2500–900, which equals 1600. a^2=1600. Now, you must find the square root of 1600 to isolate a. The square root of 1600 is 40, so a=40.
The answer is c.

We can use the Pythagorean Theorem to solve the triangle for x.
x≈20.7
Answer:
x<4
Step-by-step explanation:
multiply 2x+5 by -4. this will give you 8x+20 then subtract 20 from -12 and that gives you -8x<-32, divide by 8, flip the sign because 8 is negitive and you get x<4
X
