Plz help fast thank you very much

Answer 1

Answer:

The figure is pentagon( have 5 sides)

by the formula,

Sum of interior angles of a polygon = (number of sides of the polygon - 2) × 180

∴ sum of interior angles of pentagon = (5-2)×180°

= 540°

4 angles of the pentagon is given

∴ 5 th angle(<1)= 540°- sum of 4 angles

sum if 4 angles = (120+90+108+100)° = 418°

∴ <1= 540°-418° = 122°

<1+x= 180° [ <1 & x are linear pairs]

∴ x= 180°-122° = 58°

Answer :- x= 58°
