If a triangle has all angles less than 90° and two equal sides, what type of triangle is it?

An isosceles triangle has two sides of equal length and two equal angles. A scalene triangle has no sides of equal length and no equal angles. A right angle triangle has one angle that is 90 degrees.

Step-by-step explanation:

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

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.
