PLEASE ANSWER THIS FOR ME

Step-by-step explanation:

Once again it is trigonometry

and this time we have sides o and h valued but not a

Therefore we do not need a and are using the formula triangle o/sin*h

But we have to change this into sin=0/h to get the answer

sin=o/h

sin=19/49

sin=0.3

then now we click the 2nd function button or shift and sin with the value 0.3

this gives us 17.4

answer=17.4

23°

Step-by-step explanation:

sin ∠N= OP/NO= 19/49

⇒∠N ≈ 23°

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.
