Answer:
60
Step-by-step explanation: 12L + 1/2 = 72.5
72.5 - 24 - 8.5 + 20
72.5 -24 = 48.5 - 8.5 = 40
40 + 20 = 60
Answer:
Step-by-step explanation:
Given
sinΘ = 
= 
Then the hypotenuse = 5 and one leg of the right triangle is 3
Using Pythagoras' identity to find the second leg (x)
x² + 3² = 5²
x² + 9 = 25 ( subtract 9 from both sides )
x² = 16 ⇒ x = 4
cosΘ = 
=
