Question

plz give me solution​

Answer 1

THE ANSWER WILL BE 160°

Step-by-step explanation:

BECAUSE all the angles of the shape will be 360°

so then two angles are already given ie it is 50 and 60 degree

so now we know 2 angles

the third angle is also there as it is symbolized as as ar right angle and we know that a right angele is 90 degree

so now we know 3 angles

Now all we need to do is add the 3 angles

50 + 60+ 90 = 200

now the last angle is obviously 360 - 200 which will give you your answer

160

I REALLY HOPE IT HELPS AND PLEASE PLEASE PLEASE MARK IT AS BRAINLIEST AND SURELY PLEASE PLEASE FOLLOW ME!!!!!

Answer 2

To find:-

• Value of x

Solution:

Sum of all angles forms on straight line is equal to 180°. This statement is also known as linear pair.

So,

∠1 + 90° = 180° [Linear pair]

∠1 = 180° - 90 °

∠1 = 90°

The polygon forming is Pentagon beacuse it have five sides.

We know that,

Sum of all exterior angles of Pentagon is 360°.

So,

$\implies \sf \:60\degree + x + angle 1 + 50\degree + 90\degree= 360\degree$

$\implies \sf \:60\degree + x + 90 \degree+ 50\degree + 90\degree = 360\degree$

$\implies \sf \: x + 290\degree= 360\degree$

$\implies \sf \: x = 360\degree - 290\degree$

$\implies \sf \: x = 70\degree$

Verification:-

$\implies \sf \:60\degree + x + angle1 + 50\degree + 90\degree = 360\degree$

• Put x = 70°

$\implies \sf \:60\degree + 70\degree + 90\degree + 50\degree+ 90\degree = 360\degree$

$\implies \sf \:360\degree= 360\degree$

Therefore,

Value of x is 70°.
