Answer:
83
Step-by-step explanation:
82+87+83+77+70+80+88= 567
Then you divide that answer by the number of numbers you added by which is 7.
567/7= 81 so 83 was the missing number
Answer:
let angle AOB and angle COD be x
the it would be
x+x+110=180
2x+110=180
2x=180-110
2x=70
x=70/2
x=35 degree.
hope it will help you.
Answer:
x=4
Step-by-step explanation:
Pentagon's sum of interior angle is 540°
let's add all the given degrees
100+20x+16x+16+140+160-5x=540
Collect like terms
100+16+140+160+20x+16x-5x=540
416+31x=540
31x=540-416
31x=124
x=124/31
x=4```
Answer:
2(4 + X)
2*4 + 2*X
8+2X
