Answer: J) 28
Step-by-step explanation: Triangle interior angles equal 180°
A = p + prt
The above equation can be solved for “r” in such a way.
Subtract “p” from both sides;
A – p = p + prt – p
A – p = prt
Divide both sides by “p” and “t”;
A/pt – p/pt = prt/pt
A/pt – 1/t = r
Or
<span>r = A/pt – 1/t</span>
