The second one if im not wrong
Answer:
x = 15, Angles are both 130!
Step-by-step explanation:
Since this is an example of Alternate Exterior Angles, you could set these equal to eachother!
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 5 = 130
1 liter= 1 dm³=1000 cm³
230 cm³ = 0.23 dm³ = 0.23 lit.
If 1 gal= 3.79 lit.:
3.79 : 0.23 = 16.478 glasses of milk
Step-by-step explanation:
since the two angles are supplementary angles they add up to give 180°
therefore, 7x+2+3x-2=180°
or, 10x= 180°
or, x= 18°
