I don't get triangles

 

1. Find the area of triangle ABC if AB = 6, BC = 8, and angle ABC = 90 degrees.

 

2. If angle ABC = 135 degrees, and angle ACB = 30 degrees, what is angle BAC?

1. By the area formula for a triangle, the area is \(\frac{6 \cdot 8}{2} = 24\)

 

2. Since the sum of the angles in any triangle is \(180^\circ\), we have \(\angle{BAC} = 180^\circ - \angle{ABC} - \angle{ACB} = 180^\circ - 135^\circ - 30^\circ = 15^\circ.\)
