If ABCD Is a parallelogram, then what is the m

Step-by-step explanation:

the given shape is a parallelogram so, adjacent angles are supplementary.

so,

=》3y - 15° + 2y = 180°

=》5y = 180° + 15°

=》y = 195° ÷ 5

=》y = 39°

now , Angle A = Angle C

( they are opposite angles of a parallelogram )

=》Angle A

=》 2 × y

=》2 × 39°

=》78°

hence, Angle A = 78°

i dont have an answer

step-by-step explanation:

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°
