Question

In the figure below PQRS is a square LSR is an equilateral triangle Find the value of x + y + z

• A. ${240}^{\circ }$
• B. ${90}^{\circ }$
• C. ${105}^{\circ }$
• D. ${60}^{\circ }$

Answer 1

The correct option is A ${240}^{\circ }$

AS SQ is Straight Line, so, $\angle y+\angle x=180$
& LSR is an equilateral triangle, so, $\angle z=60$
So, $x+y+z=180+60=240$
Answer (A) 240
