Vertical angles are congruent.
2 is 153
9514 1404 393
Answer:
152°
Step-by-step explanation:
If two pairs of congruent angles total 360°, then the different angles must total 180°. The other angle measure is 180° -28° = 152°.
The measure of each angle in the other congruent pair is 152°.
Answer:
75 students
Step-by-step explanation:
first write a ratio of the students asked to students dislike
40:30, 40 to 30, or 40/30
now simplify the ratio
4/3
now she asked 40 students, so we have to find out the unit rate
so we have to flip the fraction to 3/4 and then divided the top and bottom by 4
0.75/1
now multiply the top and bottom by 100
75/100

$220.87 , (it would be $220.88 if you have to round up though
Set each expression from the parentheses equal to 0 separately like so:
Equation 1: x - 4 = 0
Equation 2: -5x + 1 = 0
Now for each equation solve for x!
Equation 1:
x +(- 4 + 4) = 0 + 4
x = 4
Equation 2:
-5x +( 1-1) = 0 - 1
-5x/ -5 = -1 / -5
x = 1/5
Check:
(4 - 4)(-5*4 + 1)
(0) (-20 + 1)
(0) (-19)
0 = 0 -------------------------> correct!
(1/5 - 4)(-5 * 1/5 + 1)
(-19/5)(-1 + 1)
(-19/5)(0)
0 = 0 -------------------------> correct!
smaller x = 1/5
larger x = 4
Hope this helped!
