Question

two angles of a quadrilateral measure 70 each and other two angles are equal. what is each angle measure​

Answer 1

answer 110'

Step-by-step explanation:

Two angles of quad. is 70' each

let , the two other equal angles be X

we know that,the sum of all the angles of a quad. is 360'.

then,

X +X + 70'+ 70'= 360'

2x+140'=360'

2x=220'

X=110'
