Use the image below to answer the following question. the sum of interior angles in this quadrilateral is_______. Therefore, I will set up the following equation to solve for x. __________.When I solve this equation, I determine that x is equal to _______. To solve for the measure of angle E, I will plug the answer I got for " x " into (5x + 3). The measure of Angle E is ________.
Answer choice:
First Line: 360 degrees, 90 degrees, 180 degrees
Second Line:
127 + (5x + 3) + (10x + 7) + 88 = 180
127 + (5x + 3) + (10x+7) + 88 = 360
5x + 3 = 10x + 7
Third Line: x=3, x=7, x= 9, x= 11
Fourth Line: 42, 45,48, 52
Answer:
First Line: 360 degrees
Second Line: 127 + (5x + 3) + (10x + 7) + 88 = 360
Third Line: x= 11
Fourth Line: 5(11) + 3 = 58
Therefore, the sum of interior angles in this quadrilateral is 360 degrees, x is equal to 11, and the measure of angle E is 58 degrees.
