Plz me ! line m is parallel to line p. m ∠ hef = 39º and m ∠ igf = 13º. find the m ∠ efg. explain in detail how you know you are correct. add additional lines and points as needed for your explanation.

39°

Step-by-step explanation

I’m pretty sure this is 39° because of the interior angle theorem.

ab will be equal to

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°
