The answer is in the image. Y is 25 because the legs are the same (45 and 45 degree angles) and x is found with trigonometry or can be √1250 (simplified as 25√ 2) using pythagorean theorem or by using 45 45 90 triangle rule.

How do I do this problem?

The formula for the circumference of a circle:
C = 2(π)(r)

To solve for r, just divide both sides by 2π.
C/2π = r

For this problem, you are given the C, so plug that into the equation.
8π = 2(π)(r)

Now to solve for r, just divide both sides by 2π
4 = r

The radius of the circle is 4.

The point slope form of the equation of the line that passes through -5,-1 and 10,-7 is y+7= -2/5(x-10). What is the standard fo

scoundrel [369]

2x + 5y = -15 is the standard form of equation

Solution:

Given that,

The point slope form of the equation of the line that passes through (-5, -1) and (10, -7) is given by:

$y + 7 = \frac{-2}{5}(x-10)$

We have to write the standard form of the equation

The standard form of an equation is Ax + By = C

In this kind of equation, x and y are variables and A, B, and C are integers

Let us convert the given equation into standard form

$y + 7 = \frac{-2}{5}(x-10)\\\\\text{Simplify the right hand side of equation }\\\\y + 7 = \frac{-2x}{5}+\frac{20}{5}\\\\y + 7 = \frac{-2x +20}{5}\\\\5(y+7) = -2x + 20\\\\\text{Simplify the left hand side of equation }\\\\5y + 35 = -2x + 20\\\\\text{Move the variables to left side of equation and constants to right side }\\\\2x + 5y = 20 - 35\\\\2x + 5y = -15$

Thus the standard form of equation is found

Answer:

a ║ c

b ║ f

Step-by-step explanation:

when parallel lines are cut by a transversal line, the supplementary angles are angles whose angle measure adds up to 180°

so answers are:

a ║ c

b ║ f
