Question

In the given angle find the angle 1,2,3,4,5

​

Answer 1

As we know that sum of interior angles of a pentagon is 540 degree.Using, that relation:-

name all the angles as x

so,

X + X + X + X + X=540°

5X=540°

X=540\5

X=18°

MEASURE OF ANGLE 1 2 3 4 AND 5 IS 18 DEGREE.

SO, ANGLE 1 + ANGLE 2 + ANGLE 3 + ANGLE 4 + ANGLE 5 IS EQUAL TO 18 + 18 + 18 + 18 + 18 =90°
