Question

in the right angle ∆ABC , ^b =90° if tan C =√3 the value of the angle A is
A 30°
B 60°
C 45°
D 15°​

Answer 1

a) a = 30 °

Step by Step

sum of all sides of triangle=180°

$\tan(60°)= \sqrt{3}$

∠c=60°

∠a+∠b+∠c=180°

∠a+90°+60°=180°

∠a+150°=180°

∠a=180°−150°

∠a=30°

Answer 2

Answer:

A 30°

Step-by-step explanation:

if tanC = √3

C = 60°

then

A + B + C = 180°

A + 90° + 60° = 180°

A = 180°-150°

A = 30°
