The values of the marked angles B , C and side , d are 41° , 49° and 19.4 meters respectively
Using the concept of Trigonometry, we can calculate the values of the angles thus ;
- Tan B = opposite/Adjacent
Tan B = 35/40
Tan B = 0.875
B = 41°
2.)
Calculate the value of angle C
C = 180 - (90 + 41) (sum of angles in a triangle)
C = 49°
3.)
Using pythagoras theorem ;
d = √40² - 35²
d = 19.36 ≈ 19.4 meters
