Answer:
40°
Step-by-step explanation:
The given triangle is a isosceles triangle . And we know that in a isosceles triangle opposite angles are equal . Therefore ,
> x + 70° + 70° = 180°
> x + 140° = 180°
> x = 180° - 140°
> x = 40°
because ( (-2)³+8))/(-2+2)=0/0,
you use formula a³+b³°(a+b)(a²-ab+b²).
therefore (x³+8)/(x+2) = ( (x+2)(x²-2x+4))/(x+2) = x²-2x+4
so lim x->-2 (x²-2x+4) = (-2)²-2*(-2)+4=
=4+4+4=12.
Answer:
38.465
Step-by-step explanation:
Area of circle =
diameter= 7
radius is half of the diameter
Radius =7÷2 = 3.5
Area = 3.14 × 3.5 × 3.5
= 38.465 inch squared
26 because if you use the formula (x+y)/2 which makes it halfway in between.
