Answer:
8² = 4² + 5² - 2(4)(5) cos(P)
which is the third option
Explanation:
The general rule of cosine is:
a² = b² + c² - 2bc*cos(A)
In our triangle:
a is substituted by p = 8 cm
b is substituted by n = 4 cm
c is substituted by m = 5 cm
A is substituted by P which we want to find
Replace the variables in the general equation with the givens as follows:
p² = n² + m² - 2mn*cos(P)
8² = 4² + 5² - 2(4)(5) cos(P)
Hope this helps :)

Answer:
$150.00
Step-by-step explanation:
Tenía $ 5.00
Mi mamá me dio $ 10.00 mientras que mi papá me dio $ 30.00.
Esto significa que luego tengo:
5 + 10 + 30 = $ 45.00
Mi tía y mi tío me dieron 100.00.
Entonces tuve:
45 + 100 = $ 145.00
Tenía otros $ 5.00.
Esto significa que en conjunto tuve:
145 + 5 = $ 150.00
