Answer:
The measurement of angel c is B.
Answer: x=3/2
Step-by-step explanation:
Answer:
c = ![\frac{b^2-R^2}{4a}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%5E2-R%5E2%7D%7B4a%7D)
Step-by-step explanation:
Given
R= ![\sqrt{b^2-4ac}](https://tex.z-dn.net/?f=%5Csqrt%7Bb%5E2-4ac%7D)
Clear the radical by squaring both sides
R² = b² - 4ac ( subtract b² from both sides )
R² - b² = - 4ac ( multiply all terms by - 1 )
b² - R² = 4ac ( divide both sides by 4a )
= c
