Question

If y and (y+20) are complementary angles find them

Answer 1

$\huge\underline{\mathbb\red{✰A}\green{N}\mathbb\blue{S}\purple{W}\mathbb\orange{E}\pink{R.}}\:$,

we know that the complementary angles is equal to 90°

than,

➠ $\textit{y + y +20 = 90°}$

➠$\textit{2y +20 = 90°}$

➠$\textit{2y = 90°- 20°}$

➠ $\textit{y = 70°/2}$

➠$\textit{y =35°}$

$\textit{first angle( y)= 35°}$

✰ $\textit{and, second (y+20)=35°+20°=55°}$
