Answer/Step-by-step explanation:
a. Unknown side, b, using the Pythagorean theorem is solved as shown below.
Unknown side, b, = 36 km
b. Perimeter of the triangle = sum of all the sides of the ∆ =
c. Area of triangle = ½*base*height
where,
Base = 36 km
Height = 27 km
C - 72 x 4
If using PEMDAS, you can already deduce the exponents and parenthesis. With these gone, you're left with multiplication and division and this is decided by which comes first from left to right. Thus, leaving you with the first multiplication problem presented.
