Question

If b=33.2 and B=61 find a

Answer 1

answer is C=18.4

solve usint the tangent

Answer 2

Alright, lets get started.

Please refer the diagram, I have attached.

As per formula SOH CAH TOA,

`Tan B = (opposite)/(adjacent)`

As per given values, angle B = 61

side b = 33.2

Putting the value back in formula

`Tan 61 = (33.2)/(a)`

Putting the value of tan 61

`1.80 = (33.2)/(a)`

Multiplying a on both sides

`a*1.80 = (33.2)/(a) * a`

a * 1.80 = 33.2

Dividing 1.80 in both sides

`(a*1.80)/(1.80) = (33.2)/(1.80)`

a = 18.4 : Answer

Hope it will help :)
