<span>The question aks us to determine which statement is always true about the angles in the figure. If angle A and B form a right angle, then C must be also a right angle, which is not correct. Also if A and C form a right angle, then angle B must be a right angle. So answers A and C are false. Also thet we know that the sum of the interior angles of the triangle is 180 degrees. A + B + C = 180 deg. ( or a straight angle ). Answer: B. Angle A, angle B, and angle C, form a straight angle. </span>

The area of circle mowed is 6644.24 square feet.

Step-by-step explanation:

Given,

Radius of circle = 46 feet

Area of circle is given by πr².

Area of circle = \pi r^2

Area of circle = 3.14*(46)^2

Area of circle = 3.14 * 2116

Area of circle = 6644.24 square feet

The area of circle mowed is 6644.24 square feet.

Find three consecutive odd integers such that six times the second decreased by twice the first is equal to twenty more than the
Kitty [74]
Let
x--------> the first <span>odd integer
x+2-----> </span>the second odd integer
x+4-----> the third odd integer

we know that
6(x+2)-2x=20+(x+2)+(x+4)
6x+12-2x=26+2x
4x-2x=26-12
2x=14
x=7

the answer is 
the numbers are
7, 9 and 11

Please help ASAP. The picture is above
Setler [38]
Every triangle’s inner angles’ addition equals to 180°
So if we find the x:
38°+x+2°+x=180°
40°+2x=180°
2x=180°-40°=140°
x=140°/2
x=70°
Now if we find the I hope this helped :)
