Question

30) and (2a) are the measures of two Supplementary angles. Find the measure of each angle
​

Answer 1

$\huge\bigstar\mathfrak\blue{\underline{\underline{SOLUTION:}}}$

Sum of two supplementary angles are 180°

So,

a+30+2a= 180°

=) 3a+30°= 180°

=) 3a= 180°-30°

=) 3a= 150°

=) a= 150°/3

=) a= 50°

Now,

1st angle, a+30= 50°+30°= 80°

2nd Angle, 2a= 2×50°= 100°

hope it helps ☺️
