Question

(a+30) ° and [2a]° are the measure of
two supplementary angle
le. What is the measure
of each angle​

Answer 1

Answer:

Measure of Supplementary Angles = 180°

(a + 30°) + (2a°) = 180°

3a + 30° = 180°

3a = 180 - 30°

3a = 150°

a = 150°/3

a = 50°

(i) a + 30°

= 50° + 30°

= 80°

(ii) 2a

= 2 × 50°

= 100°

Answer 2

Answer:

(a+30)=80 degree and (2a)= 100 degree

Step-by-step explanation:

since they are supplementary they should br equal to 180 degree,

(a+30)+(2a)=180

3a=150 degree

a=150/3=50 degree

hence first angle is 80 and second is 100
