The answer is D and not b because it’s not 90 it’s 09
Answer:
1
Step-by-step explanation:
The value of variable a, when b = 6 and c =13/2 as given in the task content is; a = 2.5.
<h3>What is the value of a when b = 6 and c =13/2?</h3>
It follows from the task content that the value of the variable, a in discuss be determined by means of the equation which relates all three variables;
a² + b² = c²
a² +6² = (13/2)²
a² = 42.25 - 36
a² = 6.25
a = 2.5
Ultimately, the value of variable a, when b = 6 and c =13/2 as given in the task content is; a = 2.5.
