The value of the missing labels B, C and d are 41° , 49° and 19.4 meters respectively
From Trigonometric concept;
- Tangent = opposite/Adjacent
Substituting our values into the relation;
Tan B = 35/40
Tan B = 0.875
B = 41° (nearest whole number value)
2.)
The value of angle C can be calculated thus ;
C = 180 - (90 + 41)
C = 49°
c.)
Using pythagoras concept ;
d = √40² - 35²
d = 19.36 ≈ 19.4 meters
