Answer:
∠ U = 70°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the circle , then
∠ U + 50° = 120° ( subtract 50° from both sides )
∠ U = 70°
The circumference of any circle is (pi) x (the diameter of the circle).
The problem gives you both numbers, so all you have to do is multiply them.
Circumference = (pi) x (diameter) = (3.14) x (21cm) = <span>65.94 cm .</span>
Answer: 68x + 36y
Step-by-step explanation:
Combine Like Terms:
= 19x + 4y + 49x + 32y
= (19x + 49x) + (4y + 32y)
= 68x + 36y
Hope this helped you!
Answer:
x is any real number
Step-by-step explanation:
The simplified form of the equation is ...
-2x -6 = -2x -2 -4
-2x -6 = -2x -6 . . . . . . . . true for any x
x is any real number.
___
The equation effectively resolves to 0x=0, which will always be true for any value of x.
