Question

the diagram shows a triangle.
what is the value of p?
p = \boxed{\circ}

Explanation:

Step1: Find the missing angle

The sum of angles in a triangle is $180^\circ$. Calculate the third angle:
$180^\circ - 99^\circ - 51^\circ = 30^\circ$

Step2: Set equal to $10p$ and solve

The missing angle equals $10p$, so:
$10p = 30$
$p = \frac{30}{10} = 3$

Answer:

$p = 3^\circ$
