Is this problem correct.

Step-by-step explanation:

it does not look correct in my eyes and it is not clear very well

Step-by-step explanation:

a) Correct

UT is a radius

also UY and UV would qualify

b) Incorrect

only VY qualifies as a diameter

c) Correct.

A diameter is a special kind of chord, the longest chord possible

XW would also qualify. A chord is a straight line that connects any two points on a circle

d) Incorrect

VY is a diameter and UT is a radius. radius is always half the length of a diameter UT = 3 units

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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°
