If it is isosceles, than the legs are the same. We will call them X. The formula for the area of a triangle is 1/2 (base * height). But the base and the height are both X. So the area (18) is equal to 1/2 (x * x), or 1/2(x^2). This means that 36 = x^2. Thus, the length of each side is 6 inches. You can check this work by plugging those into the formula for area. You will find that it equals 18.
6(3x+5)
6*3x=18x
6*5=30
<u>18x+30</u> is your answer! I hope this helped! :)

Answer:
m∠RPS = 38°.
Step-by-step explanation:
It is given that ray PT is the angle bisector of angle RPS. It means PT divides the angle RPS in two equal parts.
Now, it is clear that
Therefore, the measure of angle RPS is 38°.
