Answer:
x = 60 degrees
Step-by-step explanation:
we know x+(2x)=180
so, then we get 3x=180
x = 180/3
x = 60
I’m 15 so the answer is number 1
452.4
You can get this by first finding that the diameter of the actual foundation is 24ft. Then you can use the area of a circle formula with a radius of 12.

<u>Hence, Oprion-D is correct</u> !
Step-by-step explanation:
Since y = (x + 3)(x + 3), the root is x = -3.
Only Graph A touches the x-axis once.
