Answer:
11.5
Explanation:
Given:
Left side = 8
Bottom = a
Right side = 14
Using the Pythagorean theorem:
+
=

Simplifying the equation:
+ 64 = 196
Subtracting 64 from both sides:
= 132
Taking the square root of both sides:
a =

Calculating the approximate value of "a":
a ≈ 11.5 (rounded to the nearest tenth)
Therefore, the value of "a" in the given right triangle is approximately 11.5.
