<h3>
Answer: A) 52 square inches</h3>
==========================================================
Explanation:
a = 8, b = 13, and c = 15 are the sides of the triangle
s = (a+b+c)/2 = (8+13+15)/2 = 18 is the semi-perimeter, aka half the perimeter.
Those values are then plugged into Heron's Formula below
The triangular plaque has an area of approximately 52 square inches.
Answer:
x=7
Step-by-step explanation:
In a parallelogram, you know that parallel sides are equal in length, therefore, x+4 must equal 5x-24. From there you solve for x.
x+4 = 5x-24
28 = 4x (subtract x from both sides and add 24 to both sides)
7=x (28 divided by 4 is 7).
Answer:
The answer to this is 65
