Question

The angels of a pentagon are x^,(x+20)^,(2x-44)^and (2x-70)^. Calculate x.

Answer 1

Hyy Dude

• Given angles are x,x-10,x+20,2x-44,2x-70.

• We know that sum of interior angles of a pentagon = 540.

• x = 92.

• Therefore the value of x = 92.

Answer 2

Hyy Dude ♡

➨Sum of interior angles of pentagon=(5-2)×180°

➨3×180°=540°.

Now,

• ➨x+(x-10)+(x+20)+(2x-44)+(2x-70)=540°

• ➨7x-104=540

• ➨7x=540+104

• ➨x=644÷7

➨x=92° ans.

Hope it's helps you ♡
