A) \[70{}^\circ ,\text{ }110{}^\circ ,\text{ }80{}^\circ ,\text{ }100{}^\circ \]
B) \[70{}^\circ ,\text{ }80{}^\circ ,\text{ }110{}^\circ ,\text{ }100{}^\circ \]
C) \[70{}^\circ ,\text{ }80{}^\circ ,\text{ }100{}^\circ ,\text{ }110{}^\circ \]
D) \[80{}^\circ ,\text{ }100{}^\circ ,\text{ }110{}^\circ ,\text{ }70{}^\circ \]
Correct Answer: B
Solution :
(b): \[(2x+y)+(3x+2y)=180{}^\circ \]?????..(1) Also, \[2(x+y)+(4x-2y)=180{}^\circ \] ?????(2) Sole for ?x? and ?y? find \[\angle les\].You need to login to perform this action.
