What is the value of x? a)102 b)2 c)1 d)51

B) x = 2

Step-by-step explanation:

In the definition of a parallelogram, one factor is that opposite sides must be congruent in length.

That means that 25x + 1 = 7x + 37

Isolate x: 18x = 36

Divide: x = 2

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°
