Step-by-step explanation:
Two angles are called suplementary when their measures add to 180 degrees.
D+F= 180
3x+5+2x= 180
5x+5=180
5x= 175
x= 35°
angle D = 3x+5= 3(35)+5= <u>110°</u>
The first term of the AP i.e a = 33
and common difference i.e d = 28-33 = -5
So, 60th term = a +(n-1)d = a+ 59d
= 33 + 59( -5)
= 33- 295
= - 262
