Answer:
11.25°, 168.75°
Step-by-step explanation:
Linear pair are supplementary.
let one angle be x then the other angle is 15x, so
x + 15x = 180
16x = 180 ( divide both sides by 16 )
x = 11.25
Thus
one angle = 11.25° and the other angle = 15 × 11.25° = 168.75°
Answer:
-4/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-10-(-2))/(9-(-1))
m=(-10+2)/(9+1)
m=-8/10
simplify
m=-4/5
There are 10 digits 0 1 2 3 4 5 6 7 8 9 if we can't use 0 and 1 then there are only 8 choices for the first digit and only 2 choices for the second digit and 10 for the third so there are 8*2*10 =160 possibilities.
First square both sides
1-3x=(x+3)^2 use foil to unfactor it
1-3x=x^2+6x+9 subtract 1 from both sides
-3x=x^2+6x+8 add 3x to both sides
0=x^2+9x+8
Now that we got it equal to zero you have to factor the new trinomial
0=(x+1)(x+8)
Now since both are being multiplied by each other, if you get 1 of them to equal zero then both equal zero since 0 times anything equals 0.
So your solutions are x=-8 and x=-1

10/6 = 6/6 + 4/6 = 1 + 4/6 = 1 + 2/3
So, the simplest mixed number equaling 10/6 is 1 2/3.
