1.	x°, y°, and z°,are three angles lying on a straight line having vertices at same point.If y° is 45° and z° is 86° . Find the value of x
Answer» Answer: ${\red{\underline{\underline{\bold{<klux>GIVEN</klux>:-}}}}}$ X , Y & Z are THREE ANGLES lying on a straight line . Y = 45° Z = 86° ${\blue{\underline{\underline{\bold{To Find:-}}}}}$ Value of x ${\green{\underline{\underline{\bold{Answer:-}}}}}$ According to the Question It is given that all three angles are lying on a straight line . As we know that sum of all angles formed on a straight line is 180° . It means X + Y + Z = 180° Substitute the value we get $:\implies:$ ⟹ X + 45° + 86° = 180° $:\implies:$ ⟹ X + 131 = 180° $:\implies:$ ⟹ X = 180° -131 $:\implies:$ ⟹ X = 49° $\large\purple{{\underline{\boxed{\textbf{Hence,\:the\: value\: of\: X = 49°}}}}}$
