Question

two straight lines intersect at a point.if the sum of the measures of any three angles of the four angles produced is 290°,then find the measures of the four angles with step by step explanation.

Answer 1

Answer:

measure of four angle is 360°

three angles 290° (given)

let take angle x as fourth angle

x+290=360

x=360-290

x=70°

the fourth angle is 70°
