Answer:
The value of k is 240
Step-by-step explanation:

Or, 120 - 80 = 
Or, 40 = 
So. k = 40 × 6 = 240
Hence The value of k is 240 Answer
Sin125, on the unit circle, should be positive(not negative), since it should be in quadrant two if the angle 125 degrees is in standard position.
120+34=154
180-154=26
Angle acb=26
The answer is 10(t-1) (5t+3).
An algebraic equation of the second degree in x is a quadratic equation. Typically, a quadratic equation is expressed in standard form as,
.
And the factor is a number or algebraic expression that divides another number evenly without leaving any remainder.
To factor the given quadratic equation, first, take the common factor of the equation. Therefore,

Using the sum-product pattern, we can write 2t as 3t-5t. Therefore,

Now, find the common factor between the pairs within the bracket. We get,

Finally, rewriting the above terms by factoring out the greatest common factor, we get,
