Answer:
3 - 3/5
Step-by-step explanation:
Cosine = adjacent/hypotenuse
So, in this case, cos=6/10=3/5
Answer:
x= -9/11
or alternative form:
x= 0.81
Step-by-step explanation:
2x4-3x3-20x-21=x-3
Answer:
<h3>d. The roots are real, rational and equal.</h3>
Step-by-step explanation:
The discriminant of a quadratic equation is expressed using the equation:
D = b²-4ac. It talks about the nature of the roots of a quadratic equation.
If D>0, then the roots is real and unequal/distinct
If D<0 the roots are unreal and imaginary
If D = 0, the roots are real and equal (one real root)
According to this question, since the root given is a real value and also one value, then the the roots are real, rational and equal. Note that the root is rational since we can write it as a ratio of two integers e.g 34 = 34/1. 34 and 1 are integers

Answer:
The answer is A
Step-by-step explanation:
When two parallel lines are crossed by another line the angle of 1 will be equal to 4, 5, and 8. The angle 2 will be equal to 3, 6, and 7. Since a straight line has a degree of 180, the subtracted degree of 180-140=40 which would mean 2=40 which 2=6 so 6=40.
