Answer 1

Answer:

x= 12 units.

Step-by-step explanation:

To solve this equation, we can find each half of the base using the Pythagorean theorem. We will use 'x' as denoting each HALF of the base:

45= 3²+x²

Subtracting from both sides will give us:

36= x²

x=6.

However, the base in this problem is '2x' because 'x' is HALF of the base.

2(6)= 12 units.
