Question

two supplementary angles differ by 30 degree find the measure of each angle

Answer 1

Let the first angle be x and the second angle be y.
Then x + y = 180° ........(1)
Also, x-30 = y
= x - y = 30 .......(2)
On doing (1)-(2), We get,
2y = 150°
y = 75°
Put this value in eq (1)
x + 75° = 180°
x = 180° - 75°
x = 105°

Answer 2

Answer:

Step-by-step explanation:

let the number be x

so, now the equation will be

• x + x - 30 = 180
• 2x - 30 = 180
• 2x = 180 + 30
• 2x = 210
• x = 210 upon 2
• x = 105
• Now we have taken out the value of x , so we will put the value now.
• x - 30 , value put ..
• 105 - 30 = 75
• two supplementary angles are 105 & 75 degree
