Answer:
The measurement of angle L is given by the expression 180° – 130°. So, angle L measures 50°.
Step-by-step explanation:
The square root of 75 is 8.66, so it would be between 8 and 9
Answer:
D)
3* (2 x 8) = 3 * (8 x 2)
Step-by-step explanation:
multiplication distributes over addition.
X^2 + y^2 - x - 2*y = 0
To find both coordinates and radius we need to make this equation in circle form:
(x-a)^2 + (y-b)^2 = r^2
x^2 - 2*1/2*x + 1/4 - 1/4 + y^2 - 2*1*y + 1 - 1 = 0
Here we are adding and subtracting numbers in order to get square binomial.
(x - 1/2)^2 + (y-1)^2 = 5/4
coordinates of center are (1/2,1) and the radius is √
