X^2 + 6x +9
(x+3) (x+3)
x+3 = 0
x = -3
answer: x=-3
U just need to add it up like this 11+7+18+22+14+23.5=95.5 ft
have a nice day(:
Answer:
2/7
Step-by-step explanation:
Answer:
30°
Step-by-step explanation:
Let the measure of the missing angle be x°
Therefore, by interior angle sum postulate of a triangle:
x + 60° + 90° = 180°
x + 150° = 180°
x = 180° - 150°
x = 30°
Thus the measure of the missing angle is 30°.
