Question

90°+136°+x+35°=360°
find the value of x.​

Answer 1

→Given:  

90°+136°+x°+35°=360°

→To find:

x°

⇔All you need to do is just add which are there on the L.H.S

90+136+35+x=360

261+x=360

Now, transpose 360 to L.H.S and x to R.H.S

261-360=-x

-99=-x

- and - cancel

∴x=99°

⇔Verify:

Add all the values of L.H.S and equate to R.H.S

If they are equal, x value will be correct.

90°+136°+99°+35°=360°

∴360=360°

∴L.H.S=R.H.S

⇔The value of x is 99°
