Step-by-step explanation:
Answer:
Solution given:
a = 12, b = 5, c = 9
We have
: a² = b² + c² – 2bc cos A
12²=5²+9²-2×5×9 cos A
12²-25-81=-90 cos A
cos A=38/-90
A=cos -1(-19/45)
<u>A=115</u>°

Answer:
Step-by-step explanation:
f(x)=x²+2
a.
f(a)=a²+2+2=a²+4
b.
f(a+2)=(a+2)²+2=a²+4a+4+2=a²+4a+6
c.
f(c+d)=(c+d)²+2=c²+d²+2cd+2
The answer is d because you just need to multiply AB by 4
