Hey guys please help me find x and measure of angle.

Hey there! :)

m∠L = 80°.

Step-by-step explanation:

The shape pictured is a quadrilateral- all the interior angles sum up to 360°. Therefore:

360 - 100 - 100 - 80 = 80°.

The remaining angle has a measure of 80°.

80 degrees

Step-by-step explanation:

Since opposite angles in a rhombus are congruent, angles L and N must have equal value. Therefore, L=N=80. Hope this helps!

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.
