m and 125º are supplementary angles:
m + 125º = 180º
m = 180º <span>– 125º
</span>m = 5<span>5º <</span>——<span>— this is the answer.
I hope this helps. =)

<span>dividend x3 - 11x2 + 16x + 84
- divisor * x2 x3 - 7x2
remainder - 4x2 + 16x + 84
- divisor * -4x1 - 4x2 + 28x
remainder - 12x + 84
- divisor * -12x0 - 12x + 84
remainder 0
Quotient : x2-4x-12 Remainder: 0
Step-1 : Multiply the coefficient of the first term by the constant 1 • -12 = -12
Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is -4 .
-12 + 1 = -11
-6 + 2 = -4 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 2
x2 - 6x + 2x - 12
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-6)
Add up the last 2 terms, pulling out common factors :
2 • (x-6)
Step-5 : Add up the four terms of step 4 :
(x+2) • (x-6)
Which is the desired factorization
Final result :
(x + 2) • (x - 6) • (x - 7)</span>
Answer:
y=4x+3
Step-by-step explanation:
y=mx+b
15=4(3)+b
15=12+b
-12 -12
3=b
y=4x+3
Answer:
72%
Step-by-step explanation:
QT has length 42-24 = 18.
ST has length 42-29 = 13.
The length ST is 13/18 ≈ 72.2% of the length of QT.
