Let A and B be the two complementary angles.
A = smaller angle = 2x
B = larger angle = 13x
x = some unknown number
Note how the ratio A:B turns into 2x:13x which simplifies to 2:13
A+B = 90 ... because the angles are complementary
2x+13x = 90 ... substitution
15x = 90
x = 90/15
x = 6
A = 2*x = 2*6 = 12 degrees
B = 13*x = 13*6 = 78 degrees
The two angles are 12 degrees and 78 degrees.
Check:
A/B = 12/78 = (2*6)/(13*6) = 2/13, so A:B = 2:13
A+B = 12+78 = 90
Answer:
degree of polynomial = 5
leading term = 
leading coefficient = 2
constant term = -6
Step-by-step explanation:

(i) The degree of the polynomial = 5. That is, the highest power of x
(ii) Leading term =
. This is the term with the highest power of x.
(iii) Leading Coefficient = 2. That is, the coefficient of the leading term (
)
(iv) Constant term = -6. This is the term that is independent of x or the term in which x doesn't appear.
Answer:
For the first one the answer is 60 idk about the 2 one tho
