Question

Angle Terminology with Equations

Answer 1

If both are complementary then their sum will be 90°

$\\ \sf\longmapsto m$

$\\ \sf\longmapsto 2x-10+x-2=90$

$\\ \sf\longmapsto 2x+x-10-2=90$

$\\ \sf\longmapsto 3x-12=90$

$\\ \sf\longmapsto 3x=90+12$

$\\ \sf\longmapsto 3x=102$

$\\ \sf\longmapsto x=\dfrac{102}{3}$

$\\ \sf\longmapsto x=34$

Now

$\\ \sf\longmapsto$
