$\huge\underline\blue{Question}$

/_ABC is a isosceles triangle with

AB = AC. Find the value of x and y

$\huge\underline\blue{Given}$

AB=AC

ABC is isosceles triangle

/_BAC = 30°

$\huge\underline\blue{Concept}$

$\textbf{Sum of three angle of </p><p>triangle are}$$\textbf{equal to 180°}$

$\textbf{Sides opposite to equal angles of}$$\textbf{a triangle are equal}$

AB = AC

.•. /_x = /_y

$\huge\underline\blue{Solution}$

→x+y+A = 180°

→2x + 30° = 180

→2x = 180 - 30°

→2x = 150

→x = 150/2

→x = 75°

→x = y = 75°
