Question

Find the measure of angles 1, 2, 3, 4, 5 ,6 and 7

Answer 1

angle1=70

angle2=65

angle4=115

angle7=45

angel6=45

angle5=45

Explanation:

110+angle1 = 180

angle1 =180-70

angle1 = 70

115+angle2=180

angle2=180-115

angle2=65

angle4=115 because lines are parallel

angle1+angle2+angle7=180 because triangle

70+65+angle7=180

135+angle7=180

angle7=180-135

angle7=45

angel6=45

angle5=45
