Answer:
(x-10)° + (x + 14)° = 180°
=> x° - 10° + x° + 14 ° = 180°
=> 2x° + 4° = 180°
=> 2x° = 176°
=> x° = 176°/ 2
=> x° = 88°
Therefore the magnitude of x° = 88° (ans)

No, a cubic equation can not have three complex roots. This is because it turns twice and one end goes to positive infinity and one end goes to negative infinity. Thus, one of these MUST cross the x-axis at some point, meaning y = 0 and a real root exists.
Yes, a cubic equation can have three real roots if it cuts the x-axis three times.
Answer:
The answer is 36
Step-by-step explanation:
Answer:
x = 23
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
the third angle forms a straight angle with 100°, hence
third angle in triangle = 180° - 100° = 80°
Summing the 3 angles gives
2x + 3 + 80 + 51 = 180
2x + 134 = 180 ( subtract 134 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23
