Question

The larger of two supplementary angles exceed the smaller by 18 degrees find the angles

Answer 1

Answer:

firstangle=86°

second angle =66°

Step-by-step explanation:

let first angle be a

then second angle is a-18°

according to question

a+(a+18°) = 180°

a+a+18°=180°

2a=180°-18°

2a=172°

a=172°/2

a=86°

hence first angle is 86°

and second angle is (86°-18°)=66°

Answer 2

Answer:

$\huge\sf\fbox\pink{♡Anѕwεr♡:-}$

$\color{magenta}\pmb{Let \: the \: angles \: be \: x \: and \: y }$

$\color{magenta}\pmb{So, x + y = 180° \: \: \: \: −(1)}$

$\color{magenta}\pmb{x = y + 18}$

${\color{magenta}\pmb{ y + 18 + y = 180°}}$

${\color{magenta}\pmb{y = 81 ; \: \: x = 99°}}$
