To solve a triangle means to find the measures of the 3 angles of the triangle AND to find the lengths of the 3 sides of the triangle.
Because the sum of the angles of a triangle is 180, it is clear that angle B has measure 50.
Directrix (directrix):
So far,
<A = 40 a = ?
<B = 50 b = 6
< C = 90 c = ?
Directrix (directrix):
You have to find the lengths of sides a and c.
Use right triangle trig for this.

To help you get started, the tangent of <40 = the opposite side a over the adjacent side 6.
tan 40 = a/6
Find a. @TylerMckinney16

Hmm im not sure.

@TylerMckinney16
Crank up your calculator to get tangent of 40 degrees/
tan 40 = a/6
a = 6 * (tan 40 degrees)
a = 6 * ( ? )

Ok cool
Directrix (directrix):
It will be cool when you crank out tangent of 40 degrees.
Use this calculator:

0.839099631177??
Directrix (directrix):
Okay.
Directrix (directrix):
tan 40 = a/6
.83909 = a/6
a = 6 * (.83909 )
a = ? @TylerMckinney16

Look at the instructions and determine how the answer is to be rounded.
