Question

If one angle 18degree more than its sumplement.find the angle..........

.please solve this question first answer will be marked as brainlist​

Answer 1

Answer:

Let the first angle be x

another angle is x+18

now x+x+18 is 90

2x+18=90

2x= 72

x=72/2

=36

x=36

x-18 = 54

Answer 2

Answer:

first angle = 81°

second angle = 99°

Step-by-step explanation:

first angle = x°

second angle = x + 18°

supplementary angles = 180°

first angle + second angle = 180°

x° + (x+18)° = 180°

x° + x° + 18° = 180°

2x° + 18° = 180°

2x° = 180° - 18°

2x° = 162°

x° = 162°/2

x° = 81°

first angle = x° = 81°

second angle = x + 18° = 81 + 18 = 99°
