The Washington’s went out to eat at Salt Grass Steakhouse. Their bill was $40 plus tax. If the tax rate is 8.25%, how much did they pay in tax?

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
