Question

7th-grade math pls help! (if you're going to help pls answer what the question asks)

Answer 1

$From \:the \:given \:figure : \\100 + x = 180\degree \: [ Linear \:pair ]$

$\implies x = 180\degree - 100\degree$

$\implies x = 80\degree$

Therefore.,

$\red { Value \:of \:x } \green { = 80\degree}$

Answer 2

100°+x =180°, because it forms supplementary angle which is 180°.

X=180-100

X=80°
