Question

One angle of a quadrilateral is 150 degree and other three angles are equal. what is the measure of each of these equal angles​
a) 75 degree
b) 85 degree
c) 95 degree
d) 70 degree

Answer 1

Answer:

70 degree

Step-by-step explanation:

let the other three angles = x

so,the sum of the angles of quadrilateral =360

therefore,

150+x+x+x=360

150+3x=360

3x=360-150

3x=210

x=210/3

x=70

sor the other the angle are 70 degree
