The answer is -220
What you do is take -7 and multiply that by (1+2+3+4+5+6+7+8+9+10+11) and then after that add 11 again and multiply it by 22. It would look like this.
-7 x (1+2+3+4+5+6+7+8+9+10+11) +11 x 22
Simplify that to -7 x 66 +11 x 22
now multiply -7 and 66 to get -462
-462 +11 x 22
multiply 11 and 22
-462 + 242
and your final answer will be -220
The angles are 72 degrees and 108 degrees.
Explanation:
Angle 1 : Angle 2 = 2 : 3
Angle 1 = 2k
Angle 2 = 3k
Angle 1 + Angle 2 = 180 (supplementary angles)
2k + 3k = 180
5k = 180
k = 36
Angle 1 = 2k = 2 x 36 = 72 degrees
Angle 2 = 3k = 3 x 36 = 108 degrees
