Answer:
y=29
Step-by-step explanation:
The angles are vertical angles so they are equal.
4y-8 = 79+y
Subtract y from each side
4y-y -8 = 79+y-y
3y -8 = 79
Add 8 to each side
3y-8+8 = 79+8
3y = 87
Divide each side by 3
3y/3 = 87/3
y=29
Answer:
bigger angle is 117°
Step-by-step explanation:
x+x+54= 180 (when two angles are complementary it means that their sum is 180 degrees)
2x+54=180
2x= 180-54
2x=128
x=126/2
x= 63
x1= smaller angle
x1= 63
x2= bigger angle
x2= 63+54
x2=117
Answer:
D The value of the 2 in 12.5 is 1,000 times the value of the 2 in 0.912
Step-by-step explanation:
The value of a digit in a number can be found by setting the other digits to zero.
The value of 2 in 12.5 is 2.
The value of 2 in 0.912 is 0.002.
The ratio of values is 2.000/0.002 = 2000/2 = 1000.
The value of 2 in 12.5 is 1000 times the value of 2 in 0.912.
The correct answer is 5 because the square root of 25 is 5
