Answer:
34a + 12
Step-by-step explanation:
12a + 6a + 8 + 10a - 4 + 6a + 8
combine like terms
12a + 6a + 10a + 6a
and 8 + 8 - 4
34a + 12
Answer:
100 degrees
Step-by-step explanation:
Angle 1 + Angle 2 = 180 degrees (linear pair theorem)
Angle 2 = Angle 6 (verticle angles theorem)
Thus, we can substitute the given values of angle one and angle six into the following equation:
Angle 1 + Angle 6 = 180
4x - 20 + 5x - 25 = 180
9x - 45 = 180
9x = 225
x = 25 degrees
Angle 2 = Angle 6
5x - 25 = Angle 6, so 5x - 25 = Angle 2
5(25) - 25 = Angle 2
100 degrees = Angle 2
Answer:
80.5°
Step-by-step explanation:
Every triangle is measured to be 180°. Subtract X which is 19 from 180
180-19=161
Because V and W are congruent, they are the same length. So you divide 161 by w to get 80.5
I did another one just like this about an hour ago. I did it the elegant, tedious way,
and it took about 2 feet of screen. Then I realized there was a totally bourgeois but
easy way to do it. For 5 points, I'll give you the method for the masses:
List all the possible pairs of digits that add up to 9, along with their flips:
18 . . . . . 81
27 . . . . . 72
36 . . . . . 63
45 . . . . . 54
Do you see any pair that are different by 27 ?
How about 36 and 63 ?
So the original number is 63, and when you flip it, it becomes 36, which is 27 less.
29.10 or 29.1 is the answer rounded to the nearest hundreth
