Question

Find the measure of x . note:plz don't spam 2. most detail answer will be definitely marked as brainliest​

Answer 1

Answer:

= 180°-{90°+90°+130°+130° }

= 180°- {180°+260°}

= 180°-80°

= 80°

now,

x= 180°-100°

x= 80°

hence, the value of x is 80°

Answer 2

Answer:

Sum of interior angles in a polygon is (n-2)180°{where n is no.of sides}

So from the picture n=5 as it is a Pentagon

so sum of all interior angles=(5-2)180°=3(180°)=540°

From the diagram,

(180°-x)+90°+(180°-50°)+(180°-90°)+(180°-50°)=540°

180°-x+90°-50°-90°-50°=0

180°-x=100°

X=180°-100°=80°

Therefore measure of X is 80°
