I think the answer might be 45
Answer:
adjacent angles
complementary angles
Step-by-step explanation:
vertical angles are across from each other and equal False
adjacent angles are next to each other True
Complementary angles add to 90 degrees ( If next to each other , they form a right angle) True
Supplementary angles. add to 180 degrees, ( if next to each other, they form a straight line) False
To compare fractions you need a common denominator, then you can make a
comparison. You would divide the number line between 0 and 1 (or any 2
whole numbers on the number line) based on that common denominator. For
example... if you were trying to compare 3/4 and 2/8, you would find
the common denominator (in this case 8) and convert the fractions...
3/4 = 6/8
2/8 stays as 2/8
Now
you would go to the number line between 0 and 1 and divide it into 8
equal pieces. 3/4 would go over the 6th division and 2/8 would go over
the second division.
That would give you a good visual that 2/8 < 3/4
[ / / / / / / / ]
0 2/8 3/4 1
Answer:
x = 4±sqrt(19)
Step-by-step explanation:
Assuming you meant x^2 -8x = 3
Take the coefficient of x
-8
Divide by 2
-8/2 =-4
Square it
(-4)^2 = 16
Add this to each side
x^2 -8x +16= 3+16
The number inside the square term is the coefficient divided by 2
(x-4)^2=19
Take the square root of each side
sqrt((x-4)^2=±sqrt(19)
x-4 = ±sqrt(19)
Add 4 to each side
x-4+4 = 4±sqrt(19)
x = 4±sqrt(19)
