Question

one angle of a quadrilateral is 150 and 3 angles are equal. find the measures of the other three angles​?​

Answer 1

Step-by-step explanation:

let, the other three angle is x

So, we know that

sum of quadrilateral is 360°

= x°+x°+x°+150° = 360°

3x°+150=360°

3x=360°-150°

3x= 210°

x=210/3

x=70°

hence , the measure of the other three angle is 70°
