Question

One angle of a pentagon measures 80°. The other four angles are equal in measure. Find the measure of one of the equal angles

Answer 1

MEASURE OF FIRST ANGLE OF PENTAGON = 80°
IF ALL ANGLES R EQUAL... THEN LET THEY R EQUAL TO = X°
.


WE KNOW THAT ,
SUM OF ALL ANGLES OF PENTAGON =540°

SO, 80° + X + X + X + X =540°
80+4X = 540°
4X= 540-80
4X =460
X = 460/4
X=115° .....
