Answer:
x = 11
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
11x + 2 is an exterior angle of the triangle, then
11x + 2 = 5x + 10 + 58
11x + 2 = 5x + 68 ( subtract 5x from both sides )
6x + 2 = 68 ( subtract 2 from both sides )
6x = 66 ( divide both sides by 6 )
x = 11

um my mistake there is not any snawer choices i want to answerchoices maybe post some?
So you would do .39 times .39
that is .1521
If you round it is .152
.152 times 100 equals 15.2%
Answer:
a.
2 / 3 + 5 / 6 - 1 / 2a.
2 / 3 + 5 / 6 - 1 / 2
= 0,66... + 0,833... - 0,5
= 1,5 - 0,5
= 1
Step-by-step explanation:
sorry I only know the letter A hope I helped anyway
Hello there,
To start it off, 2 x 39= 78
So a is correct that would be 2 x 30+9 = 2x39= 78
So b is correct as well. 2 x 40-1= 2 x 39= 78
c is questionable 2 x 30 +9= 60 + 9 = 69
So d is correct 18 + 60 = 78
So e is correct 100-22 = 78
So 2 x 39 is not equal to (2 x 30) +9
Hope this helped!
