Question

Three angles of a quadrilateral are 70°65° and 73°.The fourth angle is​

Answer 1

Answer:

We

know that by sum of angles of a quadrilateral is 360 degree

x=360-270degree =9 degree

Hence 90 degree is answer

Answer 2

Answer:

152°

Step-by-step explanation:

the sum of angles of quad. is 360°

$70 + 65 + 73 + x = 360 \\ 208 + x = 360 \\ \\ x = 360 - 208 \\ = 152 \\ \\ fourth \: angle \: is \: 152$
