In δqrs, rs = 19, sq = 20, and qr = 18. which statement about the angles of δqrs must be true?

Scalene Triangle (Unequal Angles)

Step-by-step explanation:

A scalene Triangle is the one which has all three sides unequal. In the given triangle the three sides measure RS QR SQ are all unequal. A scalene Triangle has unequal angles. It has no line of symmetry. The angle opposite to the longest side is the greatest and so on.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
