Answer:
<u>b) 95 degrees</u>
Step-by-step explanation:
Remember that the internal angles of a triangle add up to 180°.
Solving :
- 45° + 40° + ∠x = 180°
- ∠x + 85° = 180°
- ∠x = <u>95 degrees</u>
2. find y'' of y = x(x+2)
y=x²+2x
y'=2x+2
3. find y'' of y = (3x+1)(x-2)
y=3x²+x-6x-2
y=3x²-5x-2
y'=6x-5
4. find y'' of y = (3x+4)squared
y=(3x+4)²
y'=2(3x+4)(3)=6(3x+4)=18x+24
5. find y' of y = 3x-2
y'=3
