When you simplify 3/12, it's 1/4.
h/8 is equal to 1/4 so you want to multiply 2 for 1/4 which it becomes 2/8
Therefore h is 2
First let's find the angles a and b.
We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.
cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.
We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.

$0.54
Step-by-step explanation:
Start by multiplying 4.5 times 1.20. That’s the normal price of the apples when they’re not on sale. $5.40. Move the decimal place back by one and you get 0.54. That’s the total price of the apples.
