Answer:
a = 36 , b = 6
Step-by-step explanation:
expand the right side using FOIL and compare coefficients with like terms on left side.
(x - b)²
= x² - 2bx + b² , compare to x² - 12x + a , then
- 2b = - 12 ( divide both sides by - 2 )
b = 6
and a = b² = 6² = 36

Answer:
Steps below
Step-by-step explanation:
The value depends on which angle is B, suppose ∠B is the opposite angle of side length 7
sin B = 7/25
cos B = 24/25
tan B = 7/24
if ∠B opposite to side length of 24
sin B = 24/25
cos B = 7/25
tan B = 24/7
