The sum of measures of angles A and B is 90°
Hence the angles are complementary
- As complementary angles have sum 90°
A) The degree of the first term is... 1

The degree of the second term is... 2

The degree of the third term is... 4

b) The leading term of the polynomial is... 7t⁴
The leading coefficient of the polynomial is... 7
c) The degree of the polynomial is... 4
Not sure for (b)
Step-by-step explanation:
(a)55+80+x=180 (angles inside the triangle)
135+×=+180
x=180-135
x=45
