Question

give me answer of this question ​

Answer 1

Answer:

72°

Step-by-step explanation:

here , it is given that the three angles are equal in the quadrilateral

so, let one angle be x° and fourth angle is 144°

now, x°+x°+x°+144° = 360°

3x°+144° = 360°

3x° = 360°-144°

3x°=216°

x°= 72°

therefore the measure of first three angles is 72°

Answer 2

Answer:

answer will 72 degree

Step-by-step explanation:

• total angle in quadrilateral is 360 degree
• according to question, three angle are equal consider them x
• so, X+X+X+144 = 360.

3X+ 144 =360

3X = 360—144

3X = 216

X = 72
