if the measure of the two opposite angles of a parallogram are: 3x + 40 and x + 50, what is the value of x and the measure of its angle
Sum of angles is:
If you measuring angles in °
8x=180° Divide with 8
In a certain triangle, one angle has a measure of 53° and another angle has a measure of 74°. If the triangle is isosceles, then which of the following could be the measure of the third angle?
