Answer:
x = 15
Step-by-step explanation:
according to Altitude Theorem, we can set up this proportion:
9/RT = RT/16
RT² = 9(16)
RT² = 144
RT = ![\sqrt{144}](https://tex.z-dn.net/?f=%5Csqrt%7B144%7D)
RT = 12
In right triangle STR, we can find 'x' by using the Pythagorean Theorem:
9² + 12² = x²
81 + 144 = x²
225 = x²
x = √225 = 15
The answer is 3.6 i know because i am a nerd
Abraham, this is the solution of the polynomials division:
5x^3 - 3x^2 + 2x - 1/ x+1
Step 1:
5x² + (-8x² + 2x - 1)/(x + 1)
Step 2:
5x² - 8x + (10x - 1)/(x + 1)
Step 3:
5x² -8x + 10 + (-11/x + 1)
The four numbers below the line are: 5 -8 10 - 11
