Problem set
1. consider the circle (x−1)^2+(y−2)^2=16. there are two lines tangent to this circle having a slope of 0.
a. find the coordinates of the points of tangency.
b. find the equations of the two tangent lines.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

if you are factoring then 4(x+3)

if you are simplifying 4x+12

step-by-step explanation:

multiply by the conjugate

the conjugate is the bottom express (6-√13) with the middle changed to +

or (6+√13)

so times it be   (6+√13)/(6+√13)

is this not q uestion reserved for the very specifics
