Part A: How many triangles and rectangles that you make? (1 point)

“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 .

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this

It means if x is -1 what is y then . check -1 on x axis and then check the value of y when x is -1

The answer is 7/8. explanation: 7/8 × 8 = 7
