I dont understand this at all, I need the right anwser and Explanation please.

a = 7; b = ⁷/2

Step-by-step explanation:

Recall the acronym, SOHCAHTOA

We would apply trigonometric ratio formula in finding a and b.

Reference angle = 60°

Opposite side to the reference angle =

Adjacent side = b

Hypotenuse = a

✔️To find a, we would apply SOH, which is:

Plug in the values

(sin 60 = √3/2)

Cross multiply

Side both sides by √3

Divide both sides by 2

a = 14/2

a = 7

✔️To find b, apply TOA, which is:

Plug in the values

(tan 60 = √3)

Cross multiply

Divide both sides by √3

Divide both sides by 2

b = 7/2

can you rephrase the question ? it is unclear : -)

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.
