Start by finding its tangent. tan Aequals=StartFraction side opposite Over side adjacent EndFraction side opposite side adjacent equals=StartFraction 73.7 Over 39.4 EndFraction 73.7 39.4 Now use a calculator to find the inverse tangent of StartFraction 73.7 Over 39.4 EndFraction 73.7 39.4. tan Aequals=StartFraction 73.7 Over 39.4 EndFraction 73.7 39.4 Aequals=61degrees° 50' (rounded).

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

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.
