Answer:
The other two equal angles of a quadrilateral are of 110° each.
Step-by-step explanation:
Let's take two angles of a quadrilateral of 70° as A and B and other two equal angles as C and D.
___________________________
We know that,
Sum of all interior angles of a quadrilateral is 360°
A + B + C + D = 360° [ Interior Angles Of Quadrilateral ]
70° + 70° + x + x = 360°
140° + 2x = 360°
2x = 360 - 140
2x = 220
x = 220 / 2
x = 110
x = 110°
C = 110°
D = 110°
The other two equal angles of a quadrilateral are of 110° each.
