Find the values of the pronumerals in this diagram. Write down the reason in each case.
timofeeve [1]

Answer:

see explanation

Step-by-step explanation:

a and 85 form a straight angle and are supplementary, thus

a + 85 = 180 ( subtract 85 from both sides )

a = 95

b and 85 are vertical angles and are congruent, thus

b = 85

c and 85 are corresponding angles and congruent, thus

c = 85

c and d are vertical angles and congruent, thus

d = 85

In conclusion

a = 95, b = 85, c = 85, d = 85

What is the equation of a circle with its center at (0,-2) and passing through the point (3,-5)
Ksivusya [100]
Circle's Standard Form Equation:
r^{2} = (x - xo)^{2} + (y - yo)^{2}

First you need to substitute the C (0,-2) in the equation, where: Xo = 0 and Yo = -2;

r^{2} = (x - 0)^{2} + (y - ( -2))^{2} \\ r^{2} = x^{2} + (y + 2)^{2}

Now you substitute the Point (3,-5) values in the last expression, where: X = 3 and Y = -5;

r^{2} = 3^{2} + (( - 5) + 2)^{2} \\ r ^{2} = 9 + ( - 3)^{2} \\ r^{2} = 9 + 9 \\ {r}^{2} = 18

Now you get the R^2 value and substitute in the equation that you found putting the C values on it:

r^{2} = x^{2} + (y + 2)^{2} \\ x^{2} + (y + 2)^{2} = 18

Here is your standard form equation of the circle.
