The image shows the construction of two tangent lines from a point outside the circle to the circle. Given that drawing the tangent lines JP and KP is step 5 in the construction and the answer choices represent steps 1 through 4, which is step 1?

A) Construct the perpendicular bisector of OP.
B) Draw a circle and a point outside the circle.
C) Draw two arcs on the circumference of the circle.
D) Draw line OP, to join the center O to point P.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

c

-by-step explanation:

it would be c

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
