When a transversal intersects with two parallel lines angles are produced. These angles will together form 4 pairs of angles .
A : 8 ; corresponding
B : 4 ; congruent
C : 2 ; adjacent
D : 4 ; similar

  A : 8 ; corresponding

Step-by-step explanation:

When two lines cross, 4 angles are produced. When a transversal crosses parallel lines, 4 angles are produced at each intersection, 8 angles total.

Angles in the same direction from the points of intersection (northeasterly direction, for example) are called corresponding angles. There are 4 pairs of corresponding angles among the 8 angles formed.

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°

y=sec x is the correct answer
