Question

What is the value of 'p' (in degrees) in the given figure?

• A. 80

Answer 1

The correct option is A 80

Angle sum of a property of a triangle:

Sum of interior angles of a triangle equal to 180°

${35}^{\circ }+{65}^{\circ }+p^{\circ }={180}^{\circ }$

$\Rightarrow {100}^{\circ }+p^{\circ }={180}^{\circ }\text{(using associative property)}$

$\Rightarrow p^{\circ }={180}^{\circ }-{100}^{\circ }\text{(subtracting 100}{}^{\circ }$
$\text{from both sides)}$

$\Rightarrow p^{\circ }={80}^{\circ }$

So, the value of p° is 80°.
