70+80+(m+10)= 180°
150+m+10=180
160+m=180
m=20°
2n-9 > 5n+2
That is the answer, I believe
9514 1404 393
Answer:
k = 7
m = 8
Step-by-step explanation:
The diagonals bisect each other, so each half is equal to the opposite half.
k +4 = 11 . . . . down-sloping diagonal
k = 7
__
m = 8 . . . . up-sloping diagonal
Because anything multiplied by one is that number. If you have 3/4 one time, then it is 3/4.
Get rid of negative exponents by remembering that x^-a= 1/x^a.
6^-3= 1/6^3
Evaluate the exponent
6^3= 216
Final answer: 1/216
