What is the next step in the proof? Choose the most logical approach. A.
Statement: ∠6 ≅ ∠14
Reason: For parallel lines cut by a transversal, corresponding angles are congruent.

B.
Statement: ∠6 ≅ ∠7
Reason: Vertical Angles Theorem

C.
Statement: ∠6 and ∠5 are supplementary.
Reason: Linear Pair Theorem

D.
Statement: m∠6 + m∠8 = 180°
Reason: angle addition

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°

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!

-une, your fren : )

it would open into a square depending on the type of envelope i’m not sure about the second part
