Answer:

B = 56

Step-by-step explanation:

A + B = 90 degrees

(6x - 8) + (5x + 21) = 90

6x - 8 + 5x + 21 = 90

(6x + 5x) + (-8 + 21) = 90

11x + 13 = 90

11x + 13 - 13 = 90 - 13

11x = 77

11x/11 = 77/11

x = 7

Plug into (5x + 21).

5(7) + 21 =

35 + 21 = 56

B = 56

  • It is not a cross-sectional study because this type of study is used to analyze characteristic of the population depending upon data but this study is not used for disease.
  • It is also not a case-control study as well as prospective cohort study because case-control study is used to observe the new cases of a disease while prospective cohort study is used for determining risks or exposure factors of a disease.
  • It is not a community trial as in which a community is under observation like a city or a country and it is also not a historical prospective cohort study because in this study type, we observe the cohorts (similar objects) with the different qualities. They are studied on the basis of these qualities.
