Question

find the area of triangle ABC if angle A is equal to 60 degree,angle b is equal to 30 degree and c b is equal to 6 cm​

Answer 1

Answer:

Step-by-step explanation:

Clearly it's a right angled triangle.hence tan b =AC/BC.so AC =2√3.hence area =1/2×2√3×6=6√3

Answer 2

Step-by-step explanation:

angle A is 60

angle B is 30

so , angle C should be 90 ( using angle sum prop. )

that means triangle is a right angled triangle...

therefore tan30 = AC / BC

1/√3 = AC / 6

AC = 6/√3

area of triangle = 1/2 * base * height

base = 6cm

height we found = 6/√3

therefore area = 1/2 * 6*6/√3 = 18/√3 cm^2

or Area = 6√3 cm^2

thank u...

hope it helps :)
