Answer:
The second one, my order is different, but they are equivalent answers
Step-by-step explanation: 6 22 22 18
(√6 + √11) / (√5 +√3) multiple top and by (√5 - √3) note the minus
(√6 + √11) × (√5 - √3) / (√5 +√3) x (√5 - √3)
(√30 + √55 - √18 - √33) / (5 - 3)
(√30 + √55 - 3√2 - √33) / 2

Answer:
The circumcentre of the circle is (0.5,-0.5)
Step-by-step explanation:
Since this is a right triangle, UW is its diameter.
<u>CONCEPT :</u> The angle subtended by the diameter at the circumference of the circle =90°
Hence , center of circle is midpoint of line segment UW.
U(-3,2) and W(4,-3)
Taking the midpoint ,
C(
Center is C(0.5,-0.5) .
Radius = CV = 
R = 
Equation of circle is 
The circumcircle of triangle is (0.5,-0.5)
solution:
One leg of the triangle is given 90ft. the other leg of the triangle is x, and the hypotenuse is given as x+30
According to Pythagoras,
C² = a² + b²
So,
(x +30) = x² + 90²
Use FOIL to expand the binomial:
x² + 60x + 900 = x² + 8100
60x = 7200
X = 7200/60
X = 120
4x=36-5x
x=4
The perimeter of the square=4x4×4
=64
