Answer:
Step-by-step explanation:
In order to solve this you just have to remember the formula for the sides and hypotenuse of the triangle rectangle:
Since A and B are equal we will use X to represent them both:
ANd by solving the equation we get that the length of the legs of the triangle rectangle with a hypotenuse of 4cm is
So first you would combine the like-terms so you get:
and combine the second like-terms:
now you only have a two step equation and you continue by doing the reciprocal and you add the -1/5 to the 24.8 where you get:
7/9x=24.6
then because the 7/9 is being multiplied by the x and your trying to isolate it you divide it by the 7/9 on both sides and you'll end up getting
x=31.628571429....

Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 6)² + (y + 1)² = 40 ← is the equation of a circle in standard form
centre = (6, - 1) and r = 
= 2
