Question

AB parallel to CD.If angle 1 =(3X—10) and angle 7=(5X-30), find the measure of angle 1 and angle 7.​

Answer 1

Answer:

angle1 =20° angle7 =20°

Step-by-step explanation:

angle 1 = angle 7

(alternate exterior angle )

so

3x -10 = 5x -30

3x -5x = -30 +10

-2x = -20

X= 10

angle1 = 3x -10 = 3×10 -10 =30-10 =20°

angle7 =5x-30 = 5×10 - 30 =50-30 = 20°
