Answer:
X + Y = 180°
Step-by-step explanation:
We know that vertical opposite angles are equal
So,
Angle A = Angle B
So,
Assume;
Angle A = x
So,
Angle A + Y = 180°
So,
X + Y = 180°
Answer:
flipping heads on a coin is a 1/2 chance, and multiples of three are 3 and 6, which is 1/3, thus, 1/2×1/3=1/5 there is a 1/5 chance Erwin will flip heads and roll a multiple of 3.
The area of a rectangle is calculated through the equation, V = L x W. That of the circle is equal to V = πr². These areas should be equal,
V = L x W = πr²
Substituting the known values,
2 ft x 11 ft = (22/7)(r²)
The value of r is sqrt 7.
