1 answer:
Draw a perpendicular line with BC from A
The line will bisect BC, and is angle A's bisector.
Call the point that bisects BC with the line is D => DAC=DAB=1/2 angle A
=> DC = 1/2*BC = 2m
=> sinDAC = DC/AC = 2/7
=> angle DAC = sin^-1(2/7) = 16.6 degrees
=> angle A = 2*DAC = 16.6 * 2 = 33.2 degrees (approx. 33 degrees)
Conclusion: B) Angle A is 33 degrees
lol ez

The answer is either or
To solve: Let's solve your equation step-by-step.
5x2+5x−x2−x=2004
Step 1: Simplify both sides of the equation.
4x2+4x=2004
Step 2: Subtract 2004 from both sides.
4x2+4x−2004=2004−2004
4x2+4x−2004=0
Step 3: Use quadratic formula with a=4, b=4, c=-2004.
x= −b±√b2−4ac /2a
x= −4±√32080 /8
