Answer:
Step-by-step explanation
larger angle = 76+2x
smaller angle = x
supplementary angles add up to 180
∴(76+2x)+x=180
76+3x=180
3x= 180-76
3x = 104
x = 104/3
x = 34.7°(smaller angle)≈ 35
larger angle = 76+2(34.7)
=76+69.4
=145.4≈ 145
Answer: 223/15
Step-by-step explanation:
Since you have exponents this is what you end up getting.
I only used the calculator for the multiplying. (Also I used * for multiplying)
(12x^4+5x^3+3x^2-5)/(x+1)
(12x*x*x*x+5x*x*x+3x*x-5)/(x+1)
(12+5+3-5)/(x+1)
(15)/(x+1)
You divide.
You get 15.
Now you add up the x's.
15x^9 plus another x because of the one in the other parentheses.
