This is incorrect. The first part subtracting 11 is correct.
However it should look like this simplifed >
Then you want to divide by 2!
Once you have done that. You get your final answer!
x = -8
Hope this helps!
Answer:
115°
Step-by-step explanation:
Knowing that the sum of all interior angles of any triangle is 180 degrees, we can find the measurement of the missing angle of the triangle. The calculation is 180 - 75 - 40 = 65. Then, notice that the blue angle and the missing angle are supplementary (linear; add up to 180 degrees). So we can find the blue angle's measurement by 180 - 65, so the answer is 115 degrees.
Answer:
Step-by-step explanation:
2x^3+16=0
2(x^3+8)=0
x^3=-8
x=-8^(1/3)
x=-2
